randrei321 Posted November 18, 2012 Share Posted November 18, 2012 I'm waiting for the UPS to deliver my new PC parts and when i took a better look at the GS600 power supply, all my plans for a good airflow got stomped. I have to make the fan point up, otherwise what's the point in getting such a good looking psu. Does the psu fan blow air into the case, or does it blow it out? Also, how shod i position the fans in my case to get the best airflow?, here is a quick sketch of the position where the fans go. how do i set it up to get the best airflow? Do i make the H60 Blow air in? Shod the top fans blow the air out? how to do it correctly? Sorry for my bad english. Link to comment Share on other sites More sharing options...

I have to make the fan point up, otherwise what's the point in getting such a good looking psu. Does the psu fan blow air into the case, or does it blow it out? The fan sucks air into the PSU and exhausts it out the back. Depending on case, fans used, airflow and so on it may slightly raise your internal case temps just because of the heat the PSU generates. However it may also lower your internal case temps by sucking the warm air from your case out the rear , but may slightly raise your PSU temps just because it is not getting the coolest air from the bottom intake of your case. We are talking just a few degrees and not much to even fret over. I have mine mounted upwards and my MB/CPU temps are still really pretty good. mid to high 30's , but I'm heavily overclocked too.*shrugs* It's going to be entirely up to you! :) http://i49.tinypic.com/173e40.jpg Link to comment Share on other sites More sharing options...
randrei321 Posted November 18, 2012 Author Share Posted November 18, 2012 hey, thanks for the reply, and wow your build looks so good, nice job! What about the top fans? do they blow air out? How about the rear fan? the one that is placed left to the cpu, and the front one? Witch blows air out and witch takes air in? Thanks in advance Link to comment Share on other sites More sharing options...
peanutz94 Posted November 19, 2012 Share Posted November 19, 2012 Thanks! I appreciate the comment! My top fans are actually exhausting out the top. The front 200mm fan is intake and the rear fan is also intake. I was actually waiting for someone to point out that it wasn't even functioning when i took the PIC, because i was working on replacing some LED's that had burnt out.:P Ideally with the RAD you would want them as intake but it really increased the dust accumulation and only changed my temps by 2deg c. That was a trade off I was willing to live with. And that is even with the PSU mounted the way it is. With the system running under prime 95 I still only hit temps in the high 60's to low 70's which very rarely happens. And,I have never had any issues with the PSU getting too hot either. I don't think you'll have any issues with too much heat, just experiment and see what works best for you!;): Link to comment Share on other sites More sharing options...
geronimo427 Posted November 19, 2012 Share Posted November 19, 2012 :sunglasse The case airflow objective is to induce a smooth and steady airflow through the case, front to back. All case and hardware fans should be directing airflow towards the rear and top(if fan(s) are installed)of the case. Otherwise, you're creating turbulence and "hot pockets" that traps dust and heat that shortens the lives of your components. Link to comment Share on other sites More sharing options...
LaRSin Posted November 19, 2012 Share Posted November 19, 2012 peanutz94 from your pic, looks like the PS and VC , are fighting for the same air, It would be better if you had a case where you could turn the ps , fan facing down , that way both will get cooler air , and your video card will run cooler and so would your power supply.. wait a minute isn't your case 650d , designed to mount the power supply fan down ? unless the ps has two fans one on each side ?

peanutz94 Posted November 20, 2012 Share Posted November 20, 2012 @geronimo427 & LaRSin, Please re-read my responses. I addressed both of your concerns as far as internal temps and dust. In MY case, I made a couple of trade offs that are not quite "Ideal", but it was something that works for me and made very little difference on both internal case temps ,PSU temps,GPU temps, and dust. (verified with an infrared temp gun) One other reason I chose to mount the PSU upwards instead of down , was because i have pets and te bottom dust filter along with the PSU were filling full of dust pretty quick, which did nothing but raise my PSU temps quite a bit. Both of which also raised my GPU temps from the extra heat the PSU was giving off.*shrugs* (again, another trade off that i was willing to live with) :) Many users choose to mount their PSU's upwards in a case that was designed to be mounted upside down and why I advised to OP to experiment and see what works best for him.:) I never said it was the "perfect" set-up.;): Cheers!

If you had read my post carefully, you would determine that you are exempt,and your scheme hasn't violated any of the desired airflow directives. Whether the psu is mounted up or down, psu air flow is still exhausted at the rear, and no back pressure is created. Link to comment Share on other sites More sharing options...
