I have a problem with my acer predator g3-710 with an NVIDIA GeForce GTX 1070...  After running normally for a while on start up, the fan will begin to run at high speed and usually then begins a cycle of "surging" where is runs a high speed for a few seconds, slows for a moment or two and then surges again.  Usuallythis occurs in a very rhythmic fashion and after bit, I can anticipate when the next surge will begin.

HWMonitor appears to indicate this is a CPU cooling issue (not the GPU).  Images will be posted below.  At the time the images were taken, all that was running was my VPN, HWMonitor and the Chrome browser.

I will also add that the incident is more likely to occur when I am gaming as opposed to web browsing or other less intensive activities.  Finally, this issue began earlier this year but, I can not pinpoint exactly when to look for software changes I may have had at the time.  No hardware changes occurred until a SSD installation last month and the issue has continued as before.  An inspection of the PC by my installer at that time found no obvious cause for the issue.

I saw another post where someone had a similar issue and applied new thermal paste.  It seemed to help for a limited time before the problem re-appeared.

Any thoughts or experience with this issue would be appreciated!




Thanks and stay safe!

    Well, it's pretty obvious that the cooling isn't ... cooling. The surging from the fan isn't surprising, it's running full to pull the temp down, the temp drops below a threshold and then the fan slows down. First step is to replace the thermal compound, and to use a good one. If that doesn't work then we'll want to look at the airflow around the heatsink.
