hi guys my msi gtx 770 tf , get 81° when gaming !! i tryed to speed up gpu fan speed from msi afterburn but the temp stayed 79/81°

I add a 4 120mm fans to my pc case , 2 in front , 1 in the left side , 1 in the back ? and i also replaced the thermal paste of gpu but the temp still 81 !!

please help me give me solution and thank's

Several questions:

1) Are you the original owner of this five year old GPU series? If so, have you always monitored its temps while gaming and only recently noticed a spike in temps?

2) When you took it apart, did you clean the cooling fan(s) and PCB free of dust? How clean is the inside of your PC from dust?

3) Is the cooler a blower design which blows the air out of the case or a dual fan cooler design where it just circulates air around the GPU from inside the case?

Again, have you only recently noticed a temp increase? Did it run cooler two years ago when you bought it from your friend? Also, what previous GPU did you have in there and did you notice it running warm? But like the other guy said, this is not a dangerous temp. It is not unusual for aging GPUs to start running hotter. Why? Because the fan motor/bearing(s) start getting gummed up with microscopic particles slowing it down - everything from human skin flakes to snack food particles to kitchen grease. The RPM monitor will not reflect this slow down because that is based on voltage use by the fan, not an actual RPM gauge like on a car.

I would look around and see if there are any aftermarket coolers that you can still buy for it. Keep in mind however you would need to ensure it fits on your exact GPU model because every video card maker has a different PCB/GPU heat pipe and location layout...that is *IF* you can still get them at all.

Did you actually increase the fan speed? MSI Afterburner and the like, are a little complicated for some to get working the way you want. Often times people adjust settings, but don't actually get them applied. Then there is the fact that the fan speed is designed on a curve, and maybe it didn't hit the temperature needed to increase the fan speed at the temp you are getting.

And lastly, 81C is the average temp of a 770 with the reference design. If not slightly low. Reference 770's run around 83C in games. That's how they are designed to run.

^^If you look at his fan RPM % in the photo, he's running at 91%. This leads me to believe his bearings are wearing out or the fan shafts are gummed up with gunk and the fans are not spinning as fast as they used to. Not unusual for an older GPU.

Any fan RPM speed increase will be noticeably louder. You'd need a decibel meter to accurately tell how much louder it is compared to what it originally was when running under high RPM.

Well again as I stated earlier, there is no guarantee that RPM reading is accurate. GPUs, at least the last time I checked, only estimate fan RPM speed based on voltage use and not an actual engine RPM gauge like a car uses. This is usually set from the factory in a test environment during development and then added to the BIOS. Monitoring software like Afterburner feed off this reading through the video card's BIOS.

So that fan may not be turning at 90%+ like it used to because the bearings are wearing out or fan shafts that go into the motor are gummed up yet the voltage use is still showing the same because it's working harder to move. Air blowing the fans and PCB will not solve that problem. It would require a complete disassembly and cleaning to remove whatever is gumming up the working parts to clean up the fan shafts. On the other hand, if the bearings are wearing out and slowing down, there's nothing he can do and it's only a matter of time before the fan motors die entirely. This is why I've never run my GPU fan speeds at over 80% because higher than that usually leads to early fan death over time. Especially if the GPU maker uses low quality fan motors.

^^There's your problem. That's what I suspected all along. That left fan is not freely spinning. That's your problem. If you can't find an aftermarket cooler for that video card, your only option is to dial back game quality settings or resolution to reduce load on the GPU to keep temps down. That fan is dying and it's only a matter of time before it will. I would start making preparations financially to replace that video card with something like a GTX 970.

Well if the fan shaft is somehow gunked up, oil will not fix it. At least not long term if the oil could even get down the shaft in the first place. The fan would need to be removed entirely then both the shaft and hole it goes into be cleaned with an alcohol based solution. That of course won't solve your problem if it's the electric motor starting to freeze up, of which there is nothing you can do about. It's really hard to tell by the video which failure it is. I have never removed a fan from a GPU so I am only speaking from listening to others who have had similar problems regarding on how to actually do it.

That said, based on one fan still freely spinning, I would strongly suspect a motor failure vs. one of the fans being full of debris/gunk.
