Gpu getting hotter and hotter each day. Possible? - Page 2

post #11 of 21
You don't have to worry about temps of 85c, that is easily within range of the thermal limit. If you still don't like it, you can get a new cooler or reapply thermal paste.

Exactly, the hot air was getting trapped and reused which increased overall temps. The positioning of your fans and whether they are intake or outtake makes the world of a difference. I currently have 10 fans in my case counting cpu and gpu coolers. 3 exhaust, 3 intake, 2 cpu fans push-pull, and a vf3000f gpu cooler with dual fans. My temps are amazing and fan noise is minimal due to using a fan controller. (GPU - 25c/55c CPU - 38c/70c idle/max) and this is at half fan speed, I could go lower but I don't like hearing a leaf blower in the background.

More fans does not equal more heat, it means more noise and more airflow. If your airflow is not moving properly then heat will increase. Reapplying thermal paste helps a lot, tim not so much but you can if you want.

Also, how can you stand your gtx 570 at 70% fan speed?

Ok, subz3ro, I like your 570/580 thread and all, but I have to ask; do you consider me stupid or something? Of course I know that better airflow means less heat. I dont know where you got that from, and honestly it makes no sense.

What do you guys think I meant by saying: "Honestly I think the added sidefan only messes up the positive pressure in my cabinet, and that in worst case scenarios (no ventilation) it kind of picks up the hot air and pumps it in again."?

This would indicate that, due to placement of the cabinet in the room, combined with the fact that the sidefan breaks the nice flow within the cabinet, the heat increases when I add an extra fan. I've had this cabinet for more than two years and am beginning to know how the air flow through it. Why preach to the choir?

brettjv seems to get what I'm saying at least.

That said, I should probably try to turn up the front intake and back fans again, to see if I can get the 570 fan down a few notches. The reason I can stand the fan at 70% is because it only kicks in at high loads, I usually wear closed headphones which block out most sounds, and I dont have to listen to it while doing other things than gaming. I also use my computer for audio recording, and I usually prefer less overall noise, and dont want to have to adjust the fan every time I use it for that purpose.

Edit: I just tried increasing the cabinet fans to medium/medium-low speeds, and imo the added noise of the air passing through the cabinet is far more annoying than the occasional 70% speed fan, which only kicks in when playing a few of my games anyways. I turned them down maybe 4-5 months ago and find that they do the job well at those speeds. Lots of people out there would find the air noise itself quite acceptable, but people are different I guess.

No, I don't consider you "stupid" or anything like that. I apologize if my response sounded like that.

I was mainly responding to james8 since it seemed like you solved your problem already.

Ah. I apologize as well, as I re-read your comment several times and thought you meant that I didnt understand the concept of airflow contra sidefan.

Sorry man. Heavy day at work, little sleep and in a sour mood when I came home.

I have 2 evga sc 570's and have noticing them running at 70c while gaming (moh, bfbc2, cod bo, metro 2033 etc) the thing that gets my attention is the fan speed being at 50%.
Is this ok? I honestly don't know but it did peak my attention when i started checking.

My temps are actually 3-4C higher without the sidefan. I'm sure difference cases,set-ups etc. etc. maybe side fans will increase temperature but this isn't an across the board thing.

Likely its just dusk build uo, use some compressed air and blow it out, i reccomend you remove the card to do this but you dont have to. ANd ensure that no fans are blocked by dust. If you temos still dont go by, remove the heatsink and reapply thermal paste. If that doesnt work, make sure that the bearings in the fan didnt go out, because in one of my 4890s the sound was about the same but one card was getting abnormally hotter and hotter each day, then i pulled the card and checked it by trying to spin the fan, it only spinned for about a 1/2 second and then stopped abruptly, emaning the bearings are gone. I replaced the heatsink, although i replaced the fan on it with another, then put the heatsink on a reference 512Mb 4850.


Long story short:
1) Clean with Compressed air
If that doesnt work
2) Put new thermal paste on card
If that doesnt work
3) Ensure Fan on card is still working







EDIT: So i guess i was a bit late....

But adding a sidefan for me cut down around 10 C* with the Setsugen coolers.

70c is no problem. My single 570 had 85 degrees on stock clock/fan speeds. They usually turn down the fan to make it less loud, at the cost of heat. Same story with my previous 280.

So, in other words, enjoy your 70c cards. They are a ok.
