Replacing fans on closed loop

post #1 of 7
Thread Starter 
So i was playing MGS V and noticed my room (in particular 2-3 feet from my rig) was rather warm. I check my thermals and here my cpu is at 58C. I reapplied thermal paste since i thought that i might of messed up the seating of the block (using h100 yes i know it was a mistake but work with what you have). temps are fine under low/medium load.

So now im thinking about finally upgrading to a push/pull in hopes that i can get bring my load temps down a bit without bringing the noise back. Was wondering if another 2 noctua f-12 fans or go buy 4 other fans (would need to be cheaper than the 2 noctuas) would be the way to go.

I guess what im asking is what would give me better temps 2 extra noctua f12s or 4 different fans and move the noctuas i currently have to front intake fans (stock case fans NZXT 140mm)?

What's your setup like?

Are the rads taking in fresh air from the outside?

If not, how about changing that first and see if there's a difference. If not, then you can invest on some better fans.

the rad is mounted inside on the top. with my CPU and GPU being pretty much right under it vertically. It being a closed loop, i dont see many options since hoses arent long enough to get the rad out of the case. itll make it about an inch past my case door.

Only option i see would be to try and mount the rad on the bottom but then i need to relocate my psu and undo all my wireties to redo cable routing (im ocd about it). But again, i think the distance is an issue.

The question was are the rad fans intake or exhaust?

Push/Pull always brings a benefit, although on a low fpi, 30mm rad the benefits are a lot less compared to a 60mm hi-fpi rad.

There is no need to have 4 identical fans (although on a Corsair it might make life easier-- if they have resolved the issue of not being able the control 4 fans).
You can have mismatched fans, as long as they are within range.
Combining a thin 15mm Scythe 600 RPM with a thick 38mm Delta 5500 RPM is not a good idea smile.gif

But the first thing to try is to make sure the fans are oriented that air from the outside of the case is sucked in through the rad, it will give you a performance boost.
Most people have their top rad/fans set to exhaust for all the wrong reasons smile.gif

My mistake guys. I misunderstood what you meant. Unfortunately i fall into the category of most people in this case. going from air to a closed loop, I never gave any thought to the fact that they should be intake. I will be changing that shortly

EDIT: I have changed it around so my 2 rad fans are intake and my idle temps are 2-4 C cooler. Load temps are looking much better. Running MGS V to compare temps before and after, temps while loading remain in high 30s and some areas it reaches 45 but thats much more acceptable. Thanks everyone!
