gtx 770 heat issues

[Looty]

Hello, it's me again.

I've had one temperature problem before, and someone told me to replace the thermal paste. So I've done that and the temps dropped around 10 degrees on the card, which I thought was great. The paste I used is Arctic-MX4. But after some time, the temperature went back to really high levels and that was only like a month after the thermal paste change.. I thought that I might've applied too little or something, so I opened the card, cleaned the paste that was there, and applied a new one. Temperatures dropped again by 10 degrees and everything was working smooth, for barely a week however. Now, the temperatures are stupid high again and I don't know what to do else.. I've used this exact same paste on my CPU and it works great for over half a year now. The temps go over 80 degrees in games, which seems pretty high, especially with the acx cooler. I know that airflow is not the problem because if I change the paste it works great for few days again. I'm kinda lost here now, thanks !

The gpu is EVGA ACX GTX 770 and I've got 4 fans in my case zalman z11. One intake in front, one fan pushing fresh air straight to the gpu, and one fan in the back and one on the top of the case as exhaust.

Thanks for any help.

Yea those are pretty high temps but that is probably just gpu boost 2.0 (which is honestly the biggest piece of shit firmware to every be released) overclocking your card to it's limit. I wouldn't worry too much about it until it get to 90 degrees. If you just don't like your card getting that hot then use a program like MSi afterburner or EVGA Precision and you can set a manual fan curve a long with a target temperature for gpu boost 2.0.

Yeah, those are high temps, but my problem is that changing the thermal paste helps for max one week, then it goes hot again. And my card doesn't overclock very much, it's a bad overclocker.. more then 50MHz bump and it crashes. Settings fans to 100% makes absolutely no difference over fans at 45%.

Well new nvidia cards overclock on a ratio (gpu boost 2.0 being another flying piece of shit) instead of linear so 50mhz ends up being a lot more. The thermal compound issue could be explained by the thermal paste just setting in. When you apply new thermal paste to something you're suppose to do a burn in run to let it get to temp and set.

 

For the fans so what you're telling me is you're getting the same temps whether your fans are at 45% or 100%? That is probably your issue, sounds like your fan aren't spinning up to the rpm they should be. You may have to RMA the card. Which EVGA has FANTASTIC customer service so I wouldn't worry too much if you have to.

I can't RMA the card straight to EVGA, I really don't have money for shipping out of my country. The fans do spin up to the RPM they should, but it doesn't make difference in the temperature.. I'm using the thermal paste on my cpu, works good there, doesn't work on a gpu. I know how the overclocking works, and it's not that. I think that the heatsink doesnt make good enough contact with the gpu die or something, but I have no idea how to fix it.
