pc is getting a too hot for my taste

[crimson2404]

I am mainly concerned with my gpu temps, one of my 6870's gets over 85c in games like metro, crysis and shogun 2.

I’d really appreciate any tips for cooling down pc, i don’t mind spending a bit of money. Already ordered a dust off can.

The case is a cm 690 ii advance.

Inside of my case

There is also a fan on the side panel i cant put in another one above because the cooler sticks out too much

Thanks

Honestly looks like you need to go at it with a can of compressed air. Pretty dusty.

Maybe get some better and/or more fans?

good cleaning and make sure the fans are blowing the proper way. Outside that water cool the gpu's

2 fans in, 3 fans out + 2 ee g cards.

you have all that dust in your case because you're not managing the route the airflows thru your case dude. you have more going out than in so its going be coming in your optical drive and power buttons and any other nook and crany it can find and with it come dust not going thru the dust filters.

you want to get some faster spinning fans on the front and bottom of your case so you can get as much air going in as is coming out dude and you want the in air to be thru filters

I said in my post that i had already ordered one.

There is one more fan i can install that hangs off the hdd cage and will blow air on the gpu’s. Thinking about getting one of these. I also might get another one to replace the side panel fan.

I’ve already ordered a dust off can and I’m not going to spend a few hundred to cool down my gpu's. The fans are blowing the right way.

I’m afraid i can’t add one on the bottom to many bloody cables there. But i will get another fan to mount on the hdd cage and replace the side panel fan.

You could manually increase the fan speed to 100% to keep it cooler.

One of them? The top one? The one whose intake is blocked by the bottom card? If that's the case, I'd get a motherboard with better organized PCI-E slots such that there is a gap between the two cards.

I don’t want my pc to be too loud

Yes it is. I am upgrading too bulldozer when its out and I have noticed in some am3+ motherboard unboxing they did have that gap and they were supplied with long crossfire bridges.

The spot fan that you have - you don't need it on your memory. Have you tried just placing it in front of the gpu's?

Hi,

I have the same case as you and am running a pair of GTX 570's - though both are of different design. Additionally my motherboard allows the cards to be spaced a little further apart than yours it appears - your airflow is rather compromised for the top card as I'm sure you're well aware.

I fitted a good high-flow high static pressure 140mm fan to the front of my case, mounted in the higher position. This feeds cool air to both cards reasonably well. After removing the lower drive cage I also added a 2nd (Antec 3 speed) 120mm fan at 45 degrees so it directed a little more air towards the upper card. This helped.

Tell me, do your cards vent most of their hot air out the back or into the case? Reason I ask is because my upper card vents out the back, while the lower card (different design) vents mostly into the case. Adding a cheap 120mm EXTRACTOR fan in the lower side-panel slot REALLY helped get the heat out of the case and prevented much of the extra heating the upper card was getting from the lower card.

During gaming / benching I can really feel the heat this extractor fan removes from the system, really rather a lot!

Typically my hottest (upper) GPU will not go any higher than very low 70's even under VERY heavy load from gaming (I find Crysis 2 heats things up) or Benching with something like Heaven 2.5 ... actually generally Crysis 2 is the hottest things I can do.

I'm not sure how much hotter/cooler our cards are when compared in the same scenario so maybe your cards would run equally hot in my case. However, what I've done has gotten the best temperatures I can out of my setup, so hopefully it'll be of use to you too.

Note: I did try the having the lower side-panel fan as INTAKE, blowing cool air directly onto the card - this was not as effective as taking the heat away...sorta makes sense really

Cheers,

Scoob.

I already did that didn’t make any difference

I’ve already said that I’m going to add a fan on the hdd cage. I was actually talking to a friend out those extractor fans and he said they took a big chunk off his gpu temp so I’m definitely going to get one of those. Thx

I think the main reason your rig is getting hotter is due to dust. The best thing to do would be to do a complete case cleaning - remove all components and clean them individually with compressed air and a dust cloth (the ones which grab on to dust forgot what they're called). You could just use compressed air without removing any parts but that wouldn't get it as clean as the former method.

Also like sheroo said the fan facing the memory is pretty useless the (the ram doesn't need it), you could try positioning to have better airflow or use them as extractor fans and also when you use compressed air don't forget to hold the fan of the component you are using the air on or the motor might burnout.

Someone cleaning out their 4870 x2 with compressed air, their temps went down from 82C load to 59C on load:

I’m going to order a can of compressed air and some fans tomorrow morning so it can come on Wednesday because that my day off.

I assume you already have the 120mm fan that came with the case? I don't think it's the best fan so a good 140mm will definitely help. Btw: you didn't mean adding a second fan to the HHD cage did you? Looking at it myself I did think of putting an additional fan on the other side of the cage. So, the main front 140mm pulling air in, drive bays, 2nd fan (120mm) attached only at two points (my lower cage isn't there any more) blowing directly on to the GPUs. Thought it might be a a bit messy though, plus space is tight with the top card and, while shorter, the bottom card has the PCI-E power connectors on the end, which might foul the fan.

Let us know how you get on.

I have the exact same case as you dude and my airflow is pretty good but I spent a good while tidying up the cbales as it makes a HUGE difference

 

[crimson2404]

WOW, I individually dusted my graphics cards and fans then the rest of my case and the top card is now 73c at max and the bottom card is 70c at max. I haven’t even installed the new fans yet and already made a huge difference.
