I was hoping to get some guidance as I am very unsure as to what the issue is, as well as how I would go about fixing it.
My build is as follows
ASUS Z-170a
GTX 1080 FTW
I7 6700
 
I recently moved and after setting my PC back up, I am having issues where my GPU fans are very inconsistent in their speeds. It mostly happens when I am in pause menus or some UI pops up in a video game like Apex, Sea of Thieves, or others. Once I get in game, the fans relax, they go slower, and they maintain one speed. However, when I am in menu, they are revving up and down like crazy, from like 20% to 100% to 50% and so on. I bought the card almost exactly 4 years ago now so I assume something in it like a regulator or something broke. I was wondering if there is a way to figure out what the issue is or if there are places like Louis Rossman but for GPUs haha.
 
Thanks for any help

Thank you for replying so fast,
 
Yes I transported it myself with it standing upright in my passenger seat buckled in XD
 
It is in a part of my room with free air flow, no obstruction what so ever.
 
I added the hysteresis and will see how that goes.
 
I am currently switched over to the aggressive fan curve from a custom low profile one I had previously set.
Unfortunately even with the aggressive profile it still does the sporadic revving. I will see how the behavior is with the adjusted hysteresis, is there any other advice to diagnose issues?

It stays at 100%, even when I am in the previously mentioned scenarios that cause the issue, it also keeps my gpu super cool ;)

UPDATE:
After lots more trouble shooting I made the discovery that during my move I set my PSU to ECO mode and that the constant up and down revving was actually my PSU and not my GPU! I switched it off and the problem is fixed. I am sorry if anyone finds this thread actually having this issue, luckily mine is now fixed

Glad your GPU is OK
