one AIO fan is upside down.


I recently built my pc and it is my first time using an AIO and after getting everything up and running a couple of days ago I noticed one of the fans on the aio is upside down. so one is blowing into the case while the other is blowing into the radiator. so far Ive had great performance and itll be a bit of a hassle to take it out again and I dont want to do it unless I know it to be neccessary.

Thanks in advanced

    Generally not ideal, but if your temps are fine it's not a major concern. The main thing is to balance the positive versus negative air pressure. Too much positive, you have excessive heat build up in the PC, as air is not exhausted properly. You may see higher temps over time when the PC is under load. Too much negative pressure is more of an issue of dust build up. Ideally, you would like to be slightly positive overall.
