Case Fan Setup with Corsair H60

[sharpshooterr05]

Hi,

I just installed my corsair h60 In Intake Mode in the back of my PC. I've read that it was not a good idea to put it that way in the back of the Case... I have a 140mm fan that I dont use yet, I though I'd put in in Exhaust mode on top of my Case Connected to my PSU since my H60 Fan is connected to CPU Fan1 and Pump to CPU Fan 2.

Here's a picture Of what I plan to do:

What are Yours Advice? Is it fine? Should I put my h60 fan in Exhaust mode Instead? and my new Fan Exhaust mode on top too?

I have a i7 4790k 4.0 Ghz Not overclocked . I use the Intel Boost Tech so Its gonna go up to 4.4 GHz in intense Game session like Pubg

Here's Msi Afterburner Result on Pubg: https://s1.postimg.org/8ertfqkqdr/PLAYERUNKNOWN_S_BATTLEGROUNDS_Screenshot_2017.10.06_-_15.31.46.7.png


I get 40 Celcius Iddles and 55 MAX In PUBG for CPU. Gpu get to 70-77 ( maybe 80 in 99% Usage) I have a 1080TI. My Psu is 600W, should I Upgrade to add a double fan on top?

Thanks, Looking fowards to your Reply

I have a couple H60s I have used on several of my builds. The way you have it in your pic is the way I have always done mine too. Fresh air intake thru the radiator and warm air exhausted out the top of the case. Hot air rises naturally anyway. The only thing I would recommend different, is that the rad fan should connect to the CPU FAN header like the stock cooler fan did. That way the BIOS can control the speed of the fan as it would normally. And as long as you have the pump connected to a header that is at 100% all the time, you're good with it.

I have the radiator fan connected to cpu_fan 1 since it's a 4 pin connected to a 4 pin connector...

The pump is connected to Cpu_fan 2 which is a 3 pin connected to a 3 pin connector.

Isnt the way its supposed to be connected? My 3rd fan which i'm gonna put exhaust on top left of the case, is connected to the power supply.

One more question, Is it a good idea to buy 2 140mm fan and connect them to the psu and put them both exhaust on top of case?

Thanks for your reply!

I must have read too fast. Didn't notice the rad fan was already connected to the CPU FAN header. I imagine though, that CPU FAN 2 is speed controlled by the BIOS just as CPU FAN 1 is. That means that the pump may slow down as the temp drops. Not a good idea with the pump. It really wants to run at full speed all the time for best cooling on the H60 and to keep the motor from burning up.

The top fan can connected directly to the PSU is fine if you don't mind the extra noise. But if you have a spare sys fan header, that would be preferable, imo. Doesn't need to be at full speed. Warm air rises. it will exit the case naturally anyway.
Whether you have 1 or 2 x 140mm fans at the top is purely a personal decision. Probably overkill, but if you like it, fine.

Alright,

I have PWR_fan, then cpu fan 1 and cpu fan 2

I have set it bios that both fan run at 100% always.

What exactly is Pwr_fan? Can i connect a fan there?

Also, is it better to put the exhaust fan on top left ( right above the radiator) OR on top right where theres not really anything except the hot heat thats gonna go Up!?

Pwr_fan is a non-controlled header that supplies a constant 12v but has the tach ability to read fan/pump speeds. Best place for the pump connector.

Corsair does things backwards for a reason. They have more faith on the longevity of the fan, than the pump. Your motherboard has a security setting with regards to cpu_fan 1. That particular header is special. No matter what the rest of the headers are set for, analog or pwm, cpu_fan1 is dedicated pwm. It's also special because it's the only header that is alarmed. If the tach reads 0 rpm (same as if there's nothing populating that header) that alarm will shut down the mobo to prevent cpu damage, or fail to allow boot process. So there must always be something in that header. Consequently Corsair has decided that since cpu_fan1 is pwm (constant 12v) and it has a 0rpm alarm, it's perfect for a pump header that'll fail before the fan does. So when the pump fails, pc shuts down, refuses to boot, you get a nice big warning about 0rpm on cpu header. This leaves sticking the fan on any other sys_fan header, which does next to nothing for fan controller.

OK, that's explained. Corsair instructions for their way of installation.

There's two large downsides to having the rear port set as an intake. No dust filter. Need to remove the radiator everytime you need to clean its face, which exponentially increases chances of leaks from multiple changes in torque on the fittings. Best bet for a rear port setting is exhaust, pull orientation if you keep the fans below @1200rpm, push orientation if 1500 or higher.

I have 2x fan ports in the top of my case, 1 is used as exhaust by my H55, the other by a 120mm fan. I don't use a rear exhaust fan at all, it's practically useless for any cooler other than a tower air cooler. It's a dinosaur leftover from the old AT standard cases. Heat rises, unless obstructed, it doesn't want to go 90° sideways. So my aio rad acts as cpu cooler exhaust and case exhaust, which it they do normally. The other exhaust is set for case temps, in a 40-50°C range, so normally doesn't even run until case temps reach 40°C, then it'll spin at 600rpm. Doesn't need to spin faster since it's above the heat source, it doesn't need the massive draw of a sideways rear exhaust, it's already fed heat from the gpu, it just helps push it out the top.

All in all, my pc is almost dead silent for the majority of the time since it's airflow characteristics are very well setup. So the fans are at minimum settings most of the time. Idle temps on an i5-3570k @4.3GHz 32°C. Gaming loads from a gtx660ti @124% user OC, cpu @54-55°C. Ambient 23°C. Cpu fan never exceeds 900rpm.

Air in front/low, air out rear/top. Creates a straight flow breeze through the case. By having opposing intakes, (aio rear rad and front intake), you need very good top exhaust or you'll end up with air fighting itself and going nowhere. Makes for hotter case temps usually, which increases gpu temp as a direct ambient result.

So should I connect the pump on pwr_fan? Or cpu fan 1 so it can alarm me when it reaches 0rpm?

Kinda dont really know what to do now, theres a guy on corsair forum that told me to put the setup like the first guy told me to put it here... so 2 guys told.me that... and you come in saying to put the h60 fan exhaust... if I put it exhaust, where should I put my 3rd fan? Since 2 exhaust fan is too much ?

Of course Corsair will tell you put pump on cpu_fan1. That way if the pump fails, you get alerted and Corsair doesn't get RMA for dead pump and bill for cooked cpu.
I personally do not install as Corsair describes because I want control of my fan. So pump goes to pwr_fan and radiator fan goes to cpu_fan1. This gives constant 12v to pump and allows the bios/software to control fan speeds.

Ok. Think orientation. If you use the aio in push orientation as an intake on the rear, this means the fan is attached to the case, the rad is attached to the fan. Air comes in the back, past the fan and through the radiator, putting the exhaust right underneath the top exhaust fan. Simple enough. But. There's no dust filter on the rear exhaust port, so all available dust is shoved through the fan to hit the backside if the radiator. Does not take long for the rad to get choked with dust. To clean it, you have to remove the radiator to get to the dirt inside. This means multiple times that you are flexing and bending the hoses, which puts pressure on the fittings. Biggest cause of leaks there is. In a pull config, it's the same, but the rad is mounted to the inside of the case, fan on inside. You still have to remove the rad to clean it properly. It's a loose-loose situation all around. Not to mention the rear exhaust sits right above the psu exhaust, so you are already sucking in heated air.

For exhaust, push is same orientation as intake pull, fan on inside. Uses air from inside the case that's already been screened for most dust by the front intake fans. Air is forced through the rad and out. To clean, just pull off the fan, not disturbing the radiator or hoses. In pull, the fan is mounted to the case, the rad on the inside. To clean, that's easy, nothing to remove at all since the face of the radiator is right there. Only heat supplied is whatever the gpu puts out.

So my advice is this. Aio either rear exhaust or top exhaust. Can do push or pull, if lower speed fans I'd do pull, high speed fans push. Led fans, push.
Air in the front, out the back/top. That's air-FLOW. Straight breeze all the way through, gets rid of the most case heat, supplies the most cooler air to replace it. Having 2x opposing intakes means the top exhaust must work 3x as hard to remove the heat supplied and still move the air from the case to the outside.
