Faulty Rx 480?

[conuk]

Hey all - have had a Sapphire Rx480 Nitro+ from new. Recently and I guess intermittently the fans go 100% - no gaming - can be youtube or actually right now posting this...

Checking CPUZ gives me the below status... so no load etc but then just ramps up for no reason. Wattman says fans are at 0 currently - have chatted with Sapphire tech ... they advised me sending video of the fans.... various driver installs... uninstall TRixx (which is now not installed)

Raised an RMA couple of days ago then all seemed fine... now it has just happened again. Am worried if I RMA the card is it will seem fine and they send it back ... anybody had any experience of an issue like this?

Ive tried to eliminate a software or driver fault.... even rebooting the system now the fan still 100% ... but I could leave it for 30 minutes and then it could calm down. I dont do a lot of gaming to be honest so hard to pinpoint.

in the graph see how it just goes full throttle ?
am running windows 10
Just RMA ?

Do you use Afterburner? Have you tried to uninstall it completely, use DDU to wipe the drivers and install fresh the 18.9.3?

Hi - have tried afterburner... Trixx ... without both... installed latest driver..... rolled back a couple.... last week tried DDU in safe mode etc... reinstalled.... thought it was ok for a couple of days ago... then something seems to make it go nuts... still at 100 .... tried cc cleaner and virus check for anything nasty... found nothing.
Also have taken out fans a while go to clean... nothing much dust wise in there.... installed back correctly.

latest gpuz ...

rebooted a couple of times... fans still at full wack... left off pc for 10 mins or so.... fans back to normal.... I bet they ramp up soon enough.... .....haha as i type ... full wack...

got to be hardware fault ?


gpuz after reboot.... and fans at 0 ... notice the blip at full wack again... then they slowing and wirring ... and now 0

Have you tried a clean install of windows? My powercolour started doing this and after a suspected malware escapade I ended up reinstalling windows, it doesn't seem to do it anymore.

I haven't to be fair... But the fans sometimes seem to go nuts at boot up and at the windows login screen.... Sometimes it goes from 0 to full at the Windows login so I would think this rules out malware?

Hard to say .. All I can say is it fixed it for me. It'll whizz up briefly on POST/startup and that's it, unless gaming when it seems to spin up as you'd expect..

But I had the exact same symptoms, it would spin up to full tilt for a couple of seconds about every 5 mins even when the PC was idle.
It didn't always do this.

Monitoring processes revealed there was some generic Windows service causing the spikes although malware can masquerade as generic Windows processes..

It could be a card fault of some sort but a clean install is probably the next logical step to isolate the issue..

My Sapphire 290 vapor-x used to do something similar. It would mostly do it when it got to windows, fans just going full speed. Leaving them for a bit or switching to manual control, then back to auto would make them go back to normal. Don't think it ever randomly did it while using the pc, was always at start up. Never did find out why, it just stopped one day.
