Corsair H100

Whats the best way to set up a h100 into a case.

my case will be the corsair 540

screw it in

Most put it in the roof, exhausting out. It's the easiest setup.

this is how I set up my mates, works fine

That's a bad idea....

The air inside the case will normally always be hotter then the air outside the case, especially if you have GPU's that vent inside the case.

You want to pull the cool air from the outside the case and push that through the radiator and into the case.

Doing that on my old set-up resulted in 10c being knocked off my load temp.

It's a trade-off. Pull cool air in through radiator; CPU will probably be cooler and GPU will most likely run hotter. Pull air out and CPU will probably be hotter and GPU will likely be cooler.

I've tried it both ways in my Phanton 410. Temps were less than a degree different on idle and only a degree different on load. The GPU however suffered a 7 degree rise with the H100i on intake

I have 3 x 120 AF series & 1 AF 140 on intake, 1 x 120 AF & 2 x 120 SP exhausting out, with the SPs being on the rad

The air in temp currently is 23.1°c, air out (after going through the rad) is 28.3°. That's with the CPU steady at 33.0°c, GPU at 28°c.

The two hottest components inside my case are the NB and the PSU (41.1 & 35.4°c respectively)

The point of my post being that the difference, at least in my system, is less than a degree on the CPU between H100i intaking or exhausting, which might as well be no difference at all but with the H100i as intake the GPU suffered greater temps.

TBH I rather have a degree on my CPU than 7 on the GPU.

I suppose if you could mount the H100i in the front then it would be slightly different but for roof mounting, my opinion, based on personal findings, is that exhaust is better all round. It's not worth the increase in temps on other components just to shave a degree from your CPU, essentially cutting your nose off to spite your face.

The point of my post is that the heated air from radiator inside of case raised your GPU temperature.. probably other components on motherboard as well. I said it was a trade-off either way, you put numbers to the difference with how it effected your system.

You can only mount the cooler on top of the 540, front mount will simply not work, tubes are too short to reach the CPU socket.

Now in terms of fan orientation, there is no definitive answer, best is to try both intake and exhaust and compare results and decide based on the data that you gather. There's just too many variables to consider to have a standard fan set up with the cooler. From ambient temp, # of GPU (xfire/SLI), case placement, case fan set up, etc.. Each set up will have its own unique cooling requirement for the user to determine if one set up is better than the other.

Most of the "how to videos" that we have released would say pull cold air outside the case then blow it through the rad, making it an intake set up.. Probably to some it'll work, but we've found out that others, it's preferred the other way around. Till we have reached a consensus that, it is best for our customer to decide as to what set up suits them best based on their own temp comparison.
