Hello,
Since a few days, I'm experiencing overheating issue on my GC. Theses are causing temperature to ramp up and then got blackscreen, I have to reboot to recover it, it only happens in games.
My configuration :
Here's the timeline and a few important points :
The thing is that in OHM, I always have Fan0 being "low speed", whereas visually, I can tell that sometimes, fan1 is slower than fan2, sometimes it's the opposite, there's no consistency
2/ Can it be a power issue ? Ie faulty connectivity that leads the computer not to be able to deliver the whole power to have fans running at 100% ?
3/ Can a temperature / tachymetric sensor be faulty ? That could lead to wrong calculations in fan speed for temperature adjustments.
EDIT : While posting this (looong
) post, I let fans to 100% in Afterburner, OHM tells me that they're around 1700-1800RPM it seems that (visually) they're really at this speed now, at least way faster than usual speed. Temperature however still peaked at 90-95°C during a game
=> Why should I kind of "warm up" my fans so they can run at full speed ?
Many thanks for your help !
Since a few days, I'm experiencing overheating issue on my GC. Theses are causing temperature to ramp up and then got blackscreen, I have to reboot to recover it, it only happens in games.
My configuration :
- Graphic card : NVIDIA GeForce GTX 970. Cooling fans : Zotac, 2x fans.
- CPU : Intel i5-6500 (3.2Ghz)
- Power unit : 500W
Here's the timeline and a few important points :
- I usually play games that my GC can handle easily (Overwatch, Apex, TW3 & so)
- Few days ago I started to play Far Cry 5, after a few hours, here the trouble begins, fans starts being noisy but didn't paid attention, I first noticed black screens (twice in 2-3h whereas I never had before)
- I then though that my drivers were outdated, did updated them and cleanup the inside of my pc (first with cottons buds & dry cleaning wipes)
- I restarted and noticed that temp is still ramping up, I cannot play anymore games I played easily before. PC smells like "hot air"
- Today, I cleaned up again, this time with dry air spray, not much improvement. My pc however is clean as it never was
- I first noticed that one of the two fans wasn't running. After a quick check, it is due to fan management from the GC that turns them only when required.
- I installed Open Hardware Monitor (OHM) to check temp & fan RPM but it seems broken, it displays for one of the fans 0 RPM whereas it is spinning (not very fast though)
- I tried Afterburner and force them to 100% all I have in OHM is : Fan1 = 119 RPM (100%), Fan 2 = 1762 RPM (100%) which is obviously wrong.
The thing is that in OHM, I always have Fan0 being "low speed", whereas visually, I can tell that sometimes, fan1 is slower than fan2, sometimes it's the opposite, there's no consistency
- When I force them to go to 100%, I hear some "clicks" after a few moment when launching a game.
- When I try to launch a game which ran smoothly before, temperature ramps up to 90°C but the fans doesn't start spinning faster. If I let the speed in "auto" in Afterburner that it increases gradually but have no impact on the visual speed. Temperature stays around 50°C when idle
2/ Can it be a power issue ? Ie faulty connectivity that leads the computer not to be able to deliver the whole power to have fans running at 100% ?
3/ Can a temperature / tachymetric sensor be faulty ? That could lead to wrong calculations in fan speed for temperature adjustments.
