Hi, i been reading all this people post and im wondering same as all you what is the best of a PSU and hope you can help me to find out my answer. my PSU is with the fan facing down(really never know if the fan is an intake or an exhaust fan, good point to know, but in case it will be an intake fan to drawn fresh air from the bottom, in this case mounted on myu HAF X) what do you think will be the result if i put it facing up sucking air from my video card and changing too the 2 fans of 200mm in the top of my case to intake air instead of exhaust air? i mean will be good cuz air flow will change to go inside from the top and the front of the case and go out to the rear. do you think this could be any good? i dont mind about my CPU temp cuz i have Corsair Hydro H80 on it so runs 20C idle and 35C load hehe, and my ram memory has memory fans from a corsair dominator airflow so i spect that air will pass from top to bottom just fine and be out from all the points in the rear of the case. hope you can help me and understand my point hehe. thanks a lot to you and all who read this and help me finding out =) by the way i have a coolermaster silent pro 700w PSU but i will changing it for a Corsair AX1200w.
Thanks a lot
amuffin is right,face the psu fan down and the top fans for exhaust,the hot air moves naturally in that direction so it will work much better,just clean the dust filter for the psu fan every few weeks or so
in a bottom mounted psu case, providing the case has a proper vent for the fan, I would place the PSU in fan facing down....just because a dropped screw inside the PSU can mean for a VERY bad day. Modern Higher wattage PSU's also benifit from the cool air coming in that hasn't been preheated by the other components of the system. a good power supply can last for a couple generations of cpu/mobos if you take care of it.
