Hi there ,
I started this week running a msi r9 270x crossfire setup in my system and am running into cooling problems with my Phanteks dx12 cpu cooler. Within 5 minutes of Crysis 3 (maxed out settings) the cpu cooler ramps up to 1850 rpm's and can just keep my temps acceptable (68c), for me that is, it's a downwards flowing config with a 140mill fan right on top of it. Would a aio like a corsair H100i or Swiftech's H220x have less problems with the gpu heat. The crossfire by the way is awsome, went from unplayable 22/27 frames to 45/54.
It will it have to fit into a Fractal r4 running a FX8350 4.62Gh.
Thank's
Eric.
I am a bit confused on how the cpu cooler is mounted. A pic would help.
I think he is either saying that the fan is pointed towards the CPU, or his case air flow flows from top to bottom. If the later is the case, you need to reverse that. if you have the cash, a 240 Rad kit can be had for $200 by alphacool.
heat rises - all exhaust should be upwards if possible
Thanks for the reactions, to be honest I started out with making myself belief there would be no overclocking and game playing :). I come from the boulderdash and sonic time and had not realy played anything beyond that time. So in first instance the phanteck's worked perfectly, untill I started running 4.62 on 1.4125 volts and putting dual gpu's in it, idle is 42*c and 74*c on a stres test. Ok thats not extreme but the noise of the fans is a bit well noisy. By the way I trayed switching the airflow around from top to bottem to bottem to top, temp difference was +2*c, like I thought it would seeing it is sucking air from two 70*c gpu's and a bit more noise. So the H100i comes in tomorrow and I'm also thinking about a future replacement of the fans with Noctua's but first I will see wat this wil do for me temp and noise wise.
Greetz,

You might also consider your case. If you have a cheap mid tower with one intake and one exhaust, your crossfire setup is just going to cook everything. So a case with good airflow means much more.
Ahum Fractal R4 isn't that cheap of a case and with 3x 140mm intake and 2x 140mm exhaust one should think there's enough breathing room.
Please can you take a pick ? My friend runs xfire 270x 4 gb and doesn't get those sorts of temps , and he runs an i5 cooled by a dark rock advanced in a pretty small case ( can't remember the model ) .
lol, did not even look at your specs. You have some issue there. Populate all the fans? Are you using the right fans for the job. Sp on coolers, airflow for case. What speeds are you running your fans.
Ya, your just sucking the heat from the gpus straight through the cpu cooler. Try mounting it in the normal fashion and make should your all intakes are populated or ramp the front fans up.The bad thing about dual fan gpus. That config would work better with blower style cooling on the gpus. Is there a fan intake at the bottom of the case? I prefer with cf a intake or exhaust on the side of case with the dual fans design. What cpu are your trying to cool with that?
Well the H100i is in and installed, just ran a stress test and 69*c after a hour of running in quiet mode. So what I was hopeing for came true, ok the fans are not the quietest one's around but Noctua will fix that later on. In max mode its like a vacuum cleaner next to you, but with these temp in quiet mode my FX8350 will be happy while playing crysis3.
