Fan won't stay at fixed speed, keeps dropping to 36%

saintdefender · 17 Apr 2014 at 13:28

I have tried a lot of stuff, I have downloaded MSI after burner and uninstalled CCC, I have tried setting to 100% which it does for about 3 seconds then drops straight down to 36 again. When playing games I can hear my fans starting up then slowing down. This happens even on desktop. There is no user defined fan curve set, this even happened in CCC without MSI installed.

I am using the latest drivers.

Any help please guys?

Thanks

EDIT:

FIXED, turns out it was a driver problem. That will teach me to avoid betas.

Glad you got it sorted, yeah beta drivers often have odd issues.

The other thing to do would have been to set a user-defined fan curve, might have fixed it

Glad you got sorted OP and is it an MSI by chance?

Yeah, a twin frozr

Interesting so this msi fan issue is even dating back 7000 series with 14.x

Guess once again I very lucky I don't have any issue with my two. I run a custom fan profile of 5% So 40c =45% and so on.

How much luck can I have?

MSI strikes again.

Gregster · 17 Apr 2014 at 14:55

What I don't get is how the fans worked perfectly on pre Mantle drivers but when the Matel drivers were released, people were seeing these fan issues. I am not blaming MSI or AMD but seems weird that the fans stopped working correctly when they worked perfectly pre 14.1.

Well you say MSI strikes again, but in fairness the 7950 has been around a while and shouldn't have these issues with new drivers.

If it only does it with AMD's new beta drivers and not with previous drivers then it has to be said it's something AMD have done/changed not something MSI have done. If it was just the one card (290 lightning's) you could argue it was a fault with MSI's new board/cooler etc but if it is affecting old hardware now too then i'm not sure MSI are 100% accountable and AMD need to take some share of the blame.

MSI has had Fan problems as far back as the 7950.

AMD may well have changed something in the Driver, and yet it has not affected anyother brand, only MSI, who have had various problems with their fans going back a year or more on AMD and Nvidia cards

Basically; if you want to avoid fan problems buy anything other than MSI cards.

I don't recall fan problems but do recall poor cooler contact and poor cooler TIM. Are you sure they had fan problems as well?

4737Joker · 17 Apr 2014 at 15:16

I too don't recall fan issues, as greg said they had some issues with the cooler conatct and TIM resulting in high temps on the twin frozr cards. iirc it was a particular batch of 7950's that happened to be on special offer at the time that was affected by said issue.

There was also a problem with them spinning up high or even 100% randomly.

It was something to do with the controller head.

Aye, iirc this was the first of the 7900 TF issues MSI had, users complaining their cards were loud due to this.

Yer, just had a look and they did have the problem of the fans ramping up and down when the card hit ~55c. This was around Feb last year and seemed to stem from another bad batch of MSI cards.

It just strikes me as odd and quite possibly MSI's fault that they are having issues with 14.x whilst the other drivers are fine. Pass

Do also note not all cards seem effected. witch again is in deed odd.

PhysicsMan94 · 17 Apr 2014 at 16:07

So many issues with MSI cards over the past year or two, glad it's being brought to light though - I'll make sure to avoid getting any MSI GPUs for the foreseeable future.

It was a diode that was causing the issue with the fans spinning at 100%

Yer, from searching, MSI said people could remove the diode to cure it themselves if they wanted to save the RMA.
