The New GPU 'Merry Christmas' Thread

As an experiment I would try putting the lower side fans on intake and the upper one on exhaust. It sounds a bit silly and I have no reason to think it would work but for the effort it would take I would try it

Snail that's a pretty good idea. Such a good idea that i think ill try it now.

EDIT

I take it you mean the two left fans.
 
That or play with higher/lower cfm fans in the different directions, the cards need feeding the cool air they're getting but little exhausting it.

Have you uprated the front and top 200mm fans too?
 
How do you know there's a pocket of warm air there?
Is it basically by touch or do you have some cool thermal imaging camera or something?

Well i know from how warm the case is getting that a lot of air is circulating around this area without much of an area to escape. If i could cut a hole in the side of the case, i know the temps would drop a bit.

I have plenty of fans, can't fit any more in. :D

However i can tweak things. This is my current setup (see link below) except ive changed the 4x1200mm side fans to intake and ive changed my rear 120mm fan to exhaust. However i might try snails suggestion now and make those two left side fans exhausts. That should help with the heat the 290's kick out the top vent.

That's the problem with positive pressure without any holes; it forms air pockets.

I would say, leave the bottom left slot on the side panel open; no fan at all. That way, the air will go where it wants to, which is usually out. It won't look pretty, but that might be the most useful course of action. Similarly, if it's open, it will pull in more air from the bottom if the cards need it, and then your problem is somewhere else anyway (you can't exhaust from that spot as then your cards would get less..)

My two cents :P
 
I see what you mean, seems like an awkward spot to cool.
When I had my HAF 932 (which has largely the same fan config options) I had the front and side as intakes and the top and rear as exhausts.
Maybe having the top fans exhausting would help shift the heat from there?
Although I see you have a H100 so all the hot air would pass through that I guess.
I'd have thought switching the rear fan around might help a bit.

Just watercool and solve that issue along with any temperature issues! :D
 
Switching the left fans to exhausts didn't really work. The top left fan was sucking out cold air, but the bottom fan was sucking out hot air. The problem was that gpu2 was running a bit cooler but gpu1 was a bit hotter.

Might try blocking off that top vent now on both cards and see what happens.

You have probably heard this before, but if you don't care about warranty too much, make the exhaust vents at the back of the cards larger :P
 
Yeah i saw that. :p

I care about my warranty though and wouldn't want to void it.



Nah about 500w-600w at stock.

Sometimes you have to think outside the box, or case in this instance. Ghetto mod time, probably won't help but worth a try. :D

What did you stick the fan on with Matt? I used stuff similar to blu tack but after a week or so the fan fell off.

You know me too well. Temps eventually peaked as they did before but got there marginally slower. Not enough difference to keep it imo. Looks like the spot fan is the next best solution.

They're not OC'd... yet. ;)

Also undervolted I think.

True and true. Under volting doesn't seem to make too much of a difference though, likely because of the offset voltage these cards now employ.

You gonna do that thread or shall i?
 
:D

I'm assuming your PSU is based to intake from below here, so:

Place a fan just over he PSU, "Under" the cards. It will not draw air from anywhere outside, but it might push the warm air on that pocket all the way up to the back exhaust. Of course it needs to be a few millimeters higher than the PSU, but just put big blu-tac blobs on the corners or something.

Why not? You seem to like ghetto mods :P

Now that is a good idea, thanks man will try it now lol.
 
I found a 1400 rpm 140mm fan worked much better than a 1500 rpm 120. The frame of the 120 blocked the card vents a bit.

Only a 120mm will fit sadly, case is not big enough too cramped.

Makes suggestion appears to have knocked 2c off the top gpu, but i need to play a longer round to test.

Time to seriously start giving water a thought matt...

I'd rather spend the money on extra//faster hardware than having slower or less hardware running cooler. Can't afford both so i choose accordingly.

Ok the Make Mod was 1c worse on temps so my original setup is still the best so far. Quite happy with it tbh as it sits happily at 90c and does not budge. Out of ideas now so will wait for the spot fan and fiddle again.
