I recently purchased a H80i on the market place with the idea of using it in my pc. I expected it to be large but didn't quite realise that is was going to be the same size as my fenrir with both fans attached. I'd like to run it with just one fan attached and as an exhaust. Anyone had any experience doing this, it would be cooling a stock 2500K.
when you do it, for ref, its not the way you think, you have to do it so that the air is brought through the h cooler, and into the case. the logic is that the air outside your case is cooler, and it needs to pass through the grill of the h unit cool. If you do it the other way, then the air in the case is warmer. so the air has to come in to the h unit from the outside and go into the case.
It should be fine, you may want to experiment on push or pull, I have an h50 which I used 1 fan on, till I got 2 for push pull. I think I got better result with push iirc. It shouldn't burst into flames... Lol
it's more effective that way, but it'll still work if it's exhausting air from inside the case out through the radiator as long as you have sufficient cool air coming in elsewhere. That's how i ran mine because the front intake was taken up by the radiator for my gpu. In fact that's how my h110i is setup now, exhausting up through the roof.
I had to resort to using 1 fan with my setup and it made no real difference....... http://forums.bit-tech.net/showthread.php?t=285741
Yup, absolutely fine. I have an H80i cooling a 4790k with only one fan in a cramped ITX case, so a 2500k will be no problem!
