|Hello! Bought a Clevo P150HM from Pro-Star in November, with a gpu upgrade to the AMD Radeon HD 6990M for gaming. Laptop has been fantastic...until last night. |
Had been running a couple of hours normally. I jumped into an online game, graphics intensive. The main fan kicked on, and jumped up to high...then stayed there. Hasn't stopped since.
(All the heavy duty gaming I've done to date, that's never happened. The main fan hardly ever comes on, and even if it does it's only for a few seconds...as if it's stepping into help out a little, and as soon as things cool off, it goes back to normal.)
Quit the game, sent the laptop to hibernate, fan powered down. Brought up from hibernate, fan immediately came on and stayed on at high speed. Tried a couple of reboots, same thing. Shut down and let it sit overnight, turned on this morning, same thing.
Downloaded the speedfan app to take a closer look.
Main fan - not listed
GPU fan - listed at 0% rpm
HD, Core 0, 1, 2, 3 - all display at low to normal temps (blue down arrow)
GPU temp ranges widely - if i'm not using graphics, it's blue down arrow, as graphics use increases, it goes to green checkmark, then red up arrow, then at its hottest in the high 50s shows a little flame. Haha, that can't be good....
From here out, working theories on my part...
Given that speedfan seems to be tracking varying gpu temp changes, and the temps seem appropriate relative to the graphics i'm using at any given time, it seems the thermal sensor is functioning normally.
Speedfan shows the GPU fan at 0% rpm, which suggests it's not working at all.
That seems to fit with what the main fan is doing. GPU heated up last night. GPU fan failed to start...so main fan jumped in to compensate. Maybe the system settings are 'stuck' now, and the main fan doesn't know it's ok to shut off. Or maybe the system is smartly doing what it should - does a safety check on startup, recognizes that the gpu fan isn't operational, and automatically leaves the main fan running to compensate. Main fan is running constantly, so all other components remain at low/normal temps, plenty well cooled.
What do you think? Does that make sense or do you have other ideas about what might be going on? (I sent an email to ProStar support of course, but they're not open until Monday.)
