I have a Lian Li PC-A16 case with 3 case fans. Front bottom of case sucking in, upper-rear blowing out, and a side-fan. They are the stock fans that came with the case. I don't know whether they are 80mm or 120mm.... I know...DUH... I'm no expert here, that's for sure.

About 2 yrs. ago or so, I bought 4 new case fans from a friend. Two are Yate Loon # D12 SL-12 (DC 12 v .30a) with a small white, square MB connector and w/ an attached molex 4 pin. The other two are Papst/ebmpapst #4412 F/2GLL, (12v, 60mA, .72W). The Papst fans only have the little white square female connector. I believe (you tell me) that these are very good fans. I want better cooling for my rig, and I think either pair will be better than the stock fans in the case now. I don't know yet if these are the right size. ...won't have to spend money...nice.

Questions:

1)Of the two, which are better for maximum cooling.
2)If the Papst is better, can I just use the small, white, square connector to the MB, and I don't need the Molex the way the Yate Loon's are set up?

Sorry for my ignorance here...

Help please

Thx

Hiyas. I'd run the panaflows on the main input and output. Be careful connecting those to the Mobo, they are high current fans, no worry to the PSU, but the Mobo might not like it. Read your Mobo book, there is usually a entry on what the fan headers are rated for. Don't use the CPU fan header rating, it's rated for more current than the rest of them. If they only have the small connectors, you can buy a fan controller, adaptors or buy pins, wires, connectors, and soldering irons.............. all sorts of fun goodies.

This place has a lot of stuff, pretty good place as far as PC stuff for wires etc.

120/80mm is very easy to figure out. Get a metric ruler and measure from one side to another................ Or if no metric ruler measure them in inches and use Google to search. Something plain as day like "inches to metric conversion". You'll get pages of nice links with java enabled converters.

The Yate Loons, if not cheap copies are very nice, cheap fans. Very popular in the PC world. But yours are low speed. I'd leave the original one in the side panel on high and blowing in.

Best place for Yates hands down is Petras. Google it.

The 2 case fans are 120x25mm. I just now replaced the front LianLi #LI121225BL-4 fan with that Papst. I notice no difference in airflow. I feel I need 2 new, more powerful fans.

Recommendations?

And will they connect to the MB the same way...small white connector?

thx...

Ohh, lots of us try to run case fans off a fan controller, it's an easy way to control fan speeds. Running fans off the Mobo is fine as long as you can set them up properly in the bios and you don't over-amp your mobo with powerful fans. It makes the smoke come out.

If your CPU temp is too high your best bet is to replace the CPU HS with a quality one, hope your still considering it. Of course having good case flow is important. Your case has just 3 120mm fans. Kinda weak by todays standards due to the heat stuff pumps out now. Think about adding MORE fans.

This thread has got me a little confused. I didn't know that a fan can mess up your mobo if connected to the wrong 3 pin header.

Conumdrum...

Yeah, you're right...I'm delaying the inevitable...do need HSF for this E6600. Liking the Xigmatek S1283...w/ pushpins/no clamp on backside of MB...

For a cpu that already has a HSF and is in the MB, what is the protocol for doing this...Remove old HSF, leave cpu in slot, place thermal paste on HS, place it on cpu, then clamp...OR... do you know a link to somewhere that takes you thru this step-by-step?

First, if you remember is remove the Mobo. You have to remove it to do it right. No 1/2 efforts when it comes to hobbies.

PULL THE MOBO OUT
Take the old cooler off, clean the CPU with alcohol, q tips etc.
Use something like Artic Clean to get it spotless.
Apply the new TIM (paste) in the proper approved, proven methods.
I use MX-2 paste, proven and pretty popular
Reinstall HS, looking at the back of the Mobo to check that the pins are properly locked

Boot it up and use an approved temp monitoring program when the CPU is at idle, should be no more than 8-10 C above ambient or so.

Then run an approved load program and check temps, stay below 60C.

I used a Thermaltake V1 for my CPU before I went water, it worked pretty good. It had pins. My temps sucked untill I realized that one of my pins were not locked properly because I didn't inspect closely enough. So I had to remove the Mobo all over again, remove the HS, clean and reapply the paste, install the HS, checking pins, then installing the mobo and hooking it all up. Yea, two hours or so. It sucked.

Push pins suck. Cheap CPU coolers suck. You don't need a TRUE and two $20 fans, but you do need decent stuff.

Research, Google is your friend.

Oh crap.... I know what's going to happen to my blood pressure when I have to remove the MB ...getting impatient, swearing, etc...

It's funny, if I do say so myself, that I'm a good athlete, having had success in several different sports over the years, HOWEVER...when it comes to this stuff...I get impatient as hell...and awkward...and I screw things up ...GEEZ.... drives me crazy...

This is why I have fought so hard not to have to remove MB, etc...

I need a few rum/cokes RIGHT NOW...

:)

As I understand the issue ragsters, some motherboard fan headers are not rated/able to handle high amperage fans. You will actually draw so much out of the header that it will die. (the header, not the fan.) I haven't heard of any other damage to the motherboard, though if it got hot enough before frying anything is possible. I'm not sure 60mA is enough to do this, though that is higher then most I think.

Hmm, my Abit AW9D manual doesn't list voltages. Older board though. I do know on most boards the CPU fan is usually rated for more amps than other fan connectors. Anyway, it's what I have learned and read over the last few years.

Brian, you got any geek freinds that like Rum n Coke? Invite them over once you talk to them. Never know. Some peeps just aren't comfortable doing stuff like this and thats okay, we all got our nitch I guess. I got started in 1983 with my C64, but was fixing electronics on fighter jets back then, so it was no biggie.

Yeah, I'm thinking of having a buddy come over and do this.

Since last night, I have checked out a much stronger 120mm case fan, the CoolerMaster # Y720CCD-25K1-GP...yikes, this thing is scary... considering getting a couple of those... or, do you think I should just get the new cpu HSF first, then see where the temps go?

YES, a stock cooler sucks. Ask your geek bud to find you a better one first, before spending money on case fans that isn't where your problem is.

Coolermaster???? Did you ever think of taking the time to look at Petras? Or even Googling case fan reviews? I can open a major can of worms and ask you to head over to xtreme forums and find their fan reviews, be prepared for tons of graphs on fans alone.

Sorry it's the way I work. At least someone (me) tells you with major dickness how it is.

I'll drink a beer with ya anytime.

I can handle it... I'm a big boy w/ thick skin...

Just ordered the E8400 cpu, Xigmatek S1283 HSF w/bracket..., and Arctic Silver... should have by early next week I hope.

Looking in open LianLi case right now....at all the STUFF I have to remove/disconnect/put back/reconnect...YIKES...need also to pick up some Captain Morgan & coke....

After all is done, then check temps....and then MAYBE upgrade the case fans...but, based on what I have been reading, very possibly not necessary...

I'm checking out the OC guide at Anandtech site...any other good ones out there for:
Asus P5B Deluxe MB
E8400
Corsair XMS2-6400C4(4-4-4-12)
PC Power & Cooling 610 Silencer PS

Thx for all your help. All ideas welcome...
