Didn't know if I should post in air or water cooling section because I'll be asking about the H100 rad.
Anyways, I decided to get an H100 mainly because of customer support. Like if anything leaks, I heard Corsair has great customer support and will replace everything it leaks on

.

Anyways, I'll be using the two Corsair fans it comes with and two Cooler Master Silent Flow (1200 rpm) . Okay here are my questions:

-Is it okay that the Corsair fans are 1300-2500rpm and the Silent Flow are only 1200rpm?
-And if so, which should be the push and pull?
-Also, should I intake fresh air, or exhaust the air out of the top?

Thanks

Probably push/pull with the variable speed on one 120.1 unit and push/pull with the fixed speed on the other. The only problem I recall Martinm mentioning was is if you made one fan spin out of specs, which you just may do if you push at 2500 rpm and have the pull fan rated at 1200 rpm.

In theory, it is better to use cooler air as intake for the fans. It is like having a cooler ambient air temperature. But in practice, total case cooling is important so you need to look at the big picture too.

Good luck.

K, thanks

Here is my current fan case setup with my CM Hyper 212+, and see if you can help me

:

rear - 120mm - exhaust
front - 140mm - intake
top - 2x120mm - both exhuast
bottom - 120mm - intake
side - 200mm - intake

So, if I made the top intake for my H-100, make my side outtake?

Hi tw23,

Often you simply have to experiment and check temperatures so we can't get too dogmatic. But if you make your top two 120's intakes (or push/pull intakes?), you will likely also want to make your 120 behind the CPU (the typical exhaust) also an intake. This would be three 120's in intake but the H100 goes through a radiator so we are not sure exactly what the cfm is on the other side.

Then the air would be pushed down over the CPU & board. I would then make the bottom 120 exhaust out and turn around the front 140 so it will exhaust. I would leave the side as intake because it is good to have air blowing on your cards and motherboard. You can always experiment with that but I have had RAM errors from heat after losing that fan from failure so it can be important.

You have changed the airflow from top to bottom. It's fine with the fans. The "heat rises" of convection doesn't apply so much in a small case with electric fans so your fans will control air flow. Chances are that any extra positive pressure will flow out through the drive bays, back grills, mesh parts, or PCI covers. It's better to have a little extra positive air-pressure than negative if only to have the dust blow out instead of being get sucked in through the cracks.

Fans are fun to play with. Once you decide on a cooling strategy, try to make only one or two changes at a time and check temps so you know. Good luck.

I just got the H100 yesterday. For push pull i would recommend using identical fans. I have mine set up as exhaust. Also i only have mine as push because i can't fit anymore fans in my phantom 410.

Push/Pull does not have to be same fans. You benefit both ways. But if you are not using same identical fans, you should put the higher fans as push, and the slower fans as pull. That way, it creates more static pressure which is good

Best Push/Pull setup for rad?

I bought two of these because for $7, why not. First of all, these definitely move more air than the fans that came with my Cooler Master case. Furthermore, they move more air than my Cooler Master...

This was the only fan that would fit in the space I had in my case between a radiator and a waterblock/pump housing. Given that I had no alternatives, i was truly please with the sound (or absence...

I replaced a loud fan in my Cooler Master Elite 430 with this. The other fan moved about the same amount of air with a far louder, higher RPM (I assume) device. This fan has a cool-looking metal...

Mouse has tracking troubles on multi-coloured pads, If you has small-medium hands it is palm or claw grip mouse. For large handed people only claw, go and buy ec1 if you want to palm.

This is not the first time that I bought these fans, however in an effeort to try and shave some degrees off my load temps, I thought I would give them another go as I was impressed with their...
