Hi
I just changed my ASUS M5A97 LE R2.0 motherboard, that died for Gigabyte GA-970A-DS3P FX V2.1. Now after changing it I have been getting insane temps compared to old setup. Before my mobo and CPU maxed out at 70-75C(usually they were mid 60s) while 1080p 60fps video editing. Now with new mobo my CPU has got to 80C and temp2 and 3 in speedfan(probably north&southbridges) has gone to 86C. In my opinion these temps are insane. In Gigabyte monitor CPU gets to 80 but system never goes over 45C.
My fan speeds(cpu and case fan both) go sometimes up to 650000(did that on old mobo also), but at least on this mobo, fans change their speeds so that isn't that big problem to me.

Are these temperatures okay for my processor and motherboard? My processor is AMD FX-8350. My cooler is Arctic Freezer 13 pro. Its heatsink doesn't get insanely hot to be honest. I can freely hold my finger on top of i while CPU is at 80C. On the other hand my northbridge heatsink gets very hot and I barely can touch it because it is just too hot.

You are right. The image I was seeing on the Gigabyte website was showing a previous version of that motherboard but the specifications listing DOES say it has 1x pwr, 2x Sys and 1x CPU, so you apparently don't have control on the 3 pin headers although that goes totally against the historical fact that when they say SYS_FAN they are generally voltage or PWM controlled and when they say PWR_FAN they are full speed.

Do NOT plug your 3 pin fans into that four pin header. There are a variety of different pin configurations and you may short something out by doing that. My suggestion would be to get a PWM controller that has 3 pin outputs, like this, which I actually am currently using myself for testing these 3 pin Aerocool DS 140 fans I...

I am sure that he was knowing what he was doing. He was just super busy and working late at night while tired can mess some things up :) My friends have also took their computers there. One thing I can think of is that he used some cheap thermal paste or did apply not enough or too much.
Anyways, it will probably take a week to deliver, because the store doesn't have my case fan in stock so they need to order it from their warehouse. Everything else is in stock, but the case fan is not 🙁
I will let you know how it went once I get the stuff and install it to my computer.
How much thermal paste do I need to apply? I hope the cooler fits my case, but if it doesn't I am just gonna cut the part with holes for side fan to take air off and then it will fit. Or take the whole side panel off. RAMs will fit, because I am using low profile RAM.
My current cooler is 159mm and H5 is 160-168mm(what exactly does that 168 mean there I have no idea, but it will fit 😀 My old case was a stock case from maybe like 2002(had still pentium 3 and 256mb ram stickers in back of it 😀) So I just took the side off and AF13 Pro fitted perfectly.

Without a fan installed in the side panel it will probably fit fine. I think that clearance issue is only when there is a fan installed on the side. If not, let me know before you go cutting up the side panel and I might have some suggestions on how to do it without it ending up looking bad.

Also, do not EVER, EVER EVER EVER EVER clip the tops off the heat pipes on the cooler itself to try and make it fit. Those heat pipes have coolant inside, usually ammonia or another rapidly evaporating liquid, which absorbs heat while in liquid form, changes to gas and moves to the other end of the heatpipe and then condenses, releasing heat to the metal and flowing back down the heatpipe to begin the process again.

https://en.wikipedia.org/wiki/Heat_pipe


Not that you would do that, but I've seen quite a few folks do it thinking that the heat pipes were just solid metal or didn't bother to think about it at all.

I will not cut the pipes 😀 My friend once did that and asked me to "repair" 😀 😀

Hah, yeah, there's no "repairing" unless you have very expensive equipment to vacuum fill and reseal the pipe, and even then you'd need to know exactly what fluid they used in it because specific fluids are used based on the properties of the design of the cooler and heat pipes. Funny how most people never seem to understand the amount of time and research goes into even the simplest seeming pieces of hardware.

Well, I haven't installed the new cooling ye, just have no time to do so right now, but I have got my parts already :) Just wanted to ask how in the wold should you install the front 120mm fan? I looked at the manual, but the manual is only about SSD/HDD on their website. Do I need ot take everything off and then put it in or can I take the front panel off and do it like that and then slap the front panel back again?

Also, a little offtopic, but I saw that on one mobo port some pins were a little bent and 1 was completely broke off. Turned out to be a usb 3.0 header(my case also has usb 3 plug, that my old mobo didnt support at all tho). I know that usb3 header has 1 unoccupied pin slot, but it is in opposite end of it. What I think is that the guy wanted to install the usb3 in repair shop, but ended up bending and breaking off some pins accidentally, because they bend quite easily I think and there is very little room in my case so it is probably hard to install something(I have installed a SSD myself and it was a bit hard).
Is it safe to keep on using my motherboard if the pins are bent in usb header. I didn't know about it at all, but just by accident looked at that direction and saw that some pins looked kinda "strange" and then realised that they are bent. The pins are not shorted or something and I will never use USB3(or any front panel usbs, because they are only usable for steering wheel or charging something 😀, read as that they are completely rubbish anyway)

Totally depends on the case model. You may have to remove drive bays and such OR on some cases you can simply remove the front panel and install it on the outer side of the front case but under the panel cover itself. Normally you want them inside the case though. I'll look into this this evening if I get a chance or if you don't figure it out before then.

Well, unfortunately, I can't find ANY information regarding the installing of the front fan, or anything else for that matter, on that case. There are no Youtube videos, no user manual on the Aerocool website except for hard drive installation, no references to that case or building on that case anyplace on the web, so you're just gonna have to figure that part out on your own I guess.

That's the problem with low end cases or manufacturers, they are usually not very helpful when it comes to features, building in their products or providing documentation or assistance, plus there generally aren't a lot of useful user uploaded videos on most less popular models. Might be something out there but I can't find it.

Either the hard drive racks have to come out of the way or the front panel might allow you to install it that way. Not sure since I can't even find a picture of that case with a front fan installed.

If you take the front panel off and post a pic, I might be able to verify how it needs to be done that way.

A little update:
Fans are installed, front panel just came off after unclipping 4 clips. Front fan and Cryo H5 installed. Applied Cryo original thermal paste because I forgot about the Arctic Silver I had bought 😀 😀 😀
Well, I had arctic Freezer 13, not the pro before and that was like 140mm I recon, pro was 159mm. Now I have 160mm fan and I can not close my case, it goes like 1 cm over 😀 I will probably just use without case.
5 minutes of prime95 and the highest temp I got was north bridge that went to about 50 degrees :) (before it was 85c in 30 seconds).
Fan speeds are fine, no bizarre speeds anymore so the old fan was the problem.
My front case fan looks nice with all those leds, but it sounds like a god damn jet engine, becasue it turns out that it is 3 pin fan not a PWM fan and it runs at full speeds. Is there any way to change speed of non pwm fan, because I want nice LEDS, but do not need front fan without the side cover on. I just ont want to unplug it, because my case looks boring without led installed.

Thank you for helping me with my fan temp problem. (Also, the cheapest thermal paste possible was used my the "professional", it was some white thermal paste, not even the one with silver 😀)

The Cryorig past is very good. No problem with using that. It's just as good as Arctic silver 5 IMO. The stock Noctua and Phanteks past is too. Most the stock pastes that come with coolers, even the Cooler Master paste (Probably better than their coolers for that matter) is ok.

Which fan is 3 pin? The back one or the front one? Are ALL your case fans 3 pin now? That front fan is one you just bought, and it's 3 pin? 3 pin can be voltage controlled for speed. It's not the fan, it's the header it's attached to that is the problem. As I told you before, the pwr_fan header is going to be full speed at all times.

The 3 pin sys_fan header on the other side of the board is a voltage controlled 3 pin and should be configurable from within the bios. You can get a 3 pin splitter to control both the front and rear fan off that header, something like this:

Back fan is pwr fan and front is 3 pin sys fan. I will try changing its speed in software.
Temps are perfect now, so are the fan speeds.
Is it ok to keep the side panel off or should I cut it bigger? It looks cool without the side panel and with fan and video card leds:)
My old heatsink was half that big, it was regular freezer 13 not pro, idk where I got that it is pro. I didnt expect the H5 to be that huge 😀
I literally have 1mm between H5's fan and my RAM and like 1 CM between my PSU and RAM 😀 basically no free room in my small case anymore lol
Sorry if I make spelling mistakes, I am using my phone right now

The only problem with having the side panel off are the risks of something (Spilled soda, coffee, dropped objects, flying hotdog, wait, what? LOL) getting in there that doesn't belong, by accident. Also, you're more likely to accumulate dust in there so you'll need to blow it out more frequently in most cases.

Be glad you only got the 120mm version. The H5, or any other 140mm cooler would have had even less room. The amount of clearance you have is ok though. In some cases it may be necessary to mount the fan just a LITTLE bit higher on the cooler to clear the RAM, but if yours is ok, then no worries.

Oh, wait, you GOT the H5 instead of the H7? No wonder you have so little space. And also no wonder your temps are really good now. That's a great cooler. Should last you through many different systems.

Do you have a top mounted power supply?

So, anyhow, the sys_fan header SHOULD be controllable and the pwr_fan should be full 12v at all times. Check in the BIOS and there should be an option to set the fan speed on the sys_fan header.

This is from the manual for your board.

Yeah, I have top mounted PSU, but it isnt that big problem for me + 1 more fan. I really dont need the front fan I recon, but that blue LED looks very good. I have used my Freezer 13 without side panel since my Windows XP days (probably like 2011 or something) and just got the bigger case this year. Believe or not, but I went 2.5 years without cleaning it :O found everything possible inside it starting from lost schoolwork and pens and ending with cat food 😀
I really dont need the side panel and it looks cool, like a window case, but looks even better :)
One more question: How in the world does my front USB 3 work fine because the professional bent 2 pins and snapped 2 off by accident on my mobo's usb3 header? I never use USB 3 anyways but just interesting to know how he got it to work :)

Can't answer that question on the USB. You SURE he snapped one off? Because that USB 3.0 internal header is SUPPOSED to be missing one pin in the corner on the end.

I'd probably go ahead and get the splitter cable, so you can connect both those fans to the voltage controlled header, even though the side panel is off, and just go ahead and set the fan profile to the very lowest setting in the bios since you don't REALLY need the front fan running for cooling purposes with the side panel off. The rear fan, even with the side panel off, you want that that one running to take the heat from the CPU cooler totally out of the case and to also create some negative pressure to draw cool air from where the side panel is not at across the motherboard etc.

He snapped 2. I see that there are 2 pins missing and 2 bent. Not the one that needs to be missing. There was little room in case and he managed to break the usb3 header

Not sure then. I would think that if any of the pins were missing, it wouldn't work right. Can you post a pic of which two are missing? Doesn't even have to be yours, just any pic and point out which two it is. Maybe I can figure out why it still works AND if it is still a problem even though it seems to work right. Could even be that the two pins were redundant or not used in all applications of the standard somehow.

Well usb 3 wire isnt even plugged in the header right now. The port works, but just not at usb 3 speeds I think.
What i am thinking is that the usb 3 on my case is fake, because he only plugged usb 2 headers and all 3 ports(including usb3) work fine

Everything has been perfectly fine since I installed the new fans.
Is there any way how to change my case fan voltage? Saw no place in my bios for that. Will look again, maybe I missed something, but I recon seeing only one system fan and changing it didn't do anything. There are 3 system fan slots, one 4 and one 3 pin slot. I have my fan connected into the 3 pin slot as it is a 3 pin fan(was advertised as PWM controlled fan tho in the place where I bought it from.

Not slots, headers. They are called headers. Headers are where you plug fan cables into. Your board has three, like I said. One says pwr_fan, one says Sys_fan and the other says CPU_fan. The one that says SYS_FAN should be the one that is controlled by the bios. There is no way to change the voltage settings for the fans, you can only change the actual fan profile settings.

The Normal setting will have slightly less than medium, medium and high speeds based on sensor temperature. The Silent will allow very low RPM operation but will still ramp up to full speed if necessary. The Manual setting will allow you to make PWM setting adjustments manually. I'd ignore that one for your setup. The other setting is disabled. Try setting that to disabled, first, so you can see if it does in fact work and shut that fan off. If it does, then you know at least part of it is working. As soon as you know that changing the setting does in fact do something, (You'll have to save settings and exit the bios for any changes to take affect, and that applies to ANY changes to ANYTHING you ever do in the bios. No bios setting changes will ever be applied until after you SAVE and exit.) then restart and go back into the bios and set it to silent. Boot into windows and see if the fan is now quieter.

If it will not disable either fan or slow down, then there is probably something wrong with the thermal sensor for the controller that handles the case fans. In either case, you might need to just get a cheap fan controller but make sure to get one specifically for use with 3 pin fans as most, but not all, of them are made for 4pin pwm fan headers.

There are 4 headers by the way.
1: CPU fan(4 pin pwm)
2: PWR fan: I have connected my back exhaust into that
3: SYS fan 1(4 pin PWM)
4: SYS fan 2: 3 pin, have plugged my front case fan into it
Should I try plugging my 3 pin into 4 pin case fan into it and see if it changes speeds that way? I have my fan profile on silent and i still rocks at full speed 🙁
In BIOS I can only change speeds of my CPU fan and 1st system fan( that is 0rpm in BIOS of course)
I don't want to unplug the fan completely, because these LEDs look quite cool on my case

Probably somewhat overkill for your needs but I don't really see any other PWM controllers that let you use 3 pin fans so there isn't a lot of options if you want to avoid buying fans.:

The only other options you have, I think, would be replacing those fans with 4 pin PWM fans or disconnecting them, which is not a good option.
