Graphics card's fans don't turn on until 90'C

This concerns my 5 year old MSI Radeon HD 7850. So I've noticed a couple months ago how my card got a lot louder than usual. It seemed to randomly spin up to full speed and then stop when I played games. This is on my old 8 year old PC, of which I thought was causing some bios or driver setting to cause this problem.

A week ago I built my brand new PC. I upgraded everything but the graphics card (because bitcoin fuckers inflated the prices). After a while running on my 8600k's integrated graphics (which aren't that bad?!) I decided to plop in my old graphics card to squeeze any more performance out of it before I get a new one. The issue hadn't resolved itself.

The card only starts to turn on the fans when the GPU's temp reaches 90'C; only to immediately turn them off when it reaches 80'C. What do you guys think I should do?

- Update GPU drivers to latest version first.

- You can use MSI afterburner to manually set a fan speed curve. You can also use it to test your fans at various speeds to make sure they are in working order. If the fans do not follow your fan curve you created then there is a a physical issue with either the fans on the card or the graphics card's BIOS.

If it does not turn on until 90C even after a fresh driver update or unless you max out the fan profile in MSI afterburner, that usually indicates that the 5v fed to the fan is dead or the 5v wire is broken or the graphics card fan header is broke.

If it work at 100% fan speed, then you will probably have to set it to 100% fan speed when you play something demanding, at least until you get a new graphics card, might be loud but it will keep it from throttling at 90C.
