GPU running much hotter than before with flash but normal under load?

[Techhog]

So, today, I noticed that, for whatever reason, flash video now makes my 7950 run at 46C compared to just 33-38C before. Idle without flash is 37C right now, which is about normal on days when my room is a little hotter than normal due to the radiator going overboard. However, my load temps are still the same (60-65C with the case fans on full speed), so that makes dust buildup seem a bit unlikely. Any idea of what may be going on?

Do you know what clocks it is running on idle, You can use GPU-Z or Aida to monitor those values. It is suppose to be at 300mhz Core / 150mhz memory on idle

Sometime, different BIOSes have different clock states.

Why did you flash you BIOS in the first place?

Did the fan speed stay the same @ idle?

Flash is hardware accelerated.

Any updates?

I would guess the flash update included tuned memory settings for the video memory? So, when you run flash, the GPU increases the video memory speed, and then the new (maybe more aggressive/mining friendly?) memory settings generate more heat?

I think he should monitor his clock states (core and memory) on idle.

I notice that kind of behavior a couple of times. As example, my R9 290x. On the stock BIOS, the idle clocks are 300mhz/150mhz and if I flash to my benchmark BIOS, the PT1 or PT3, the idle clocks will remain at 1000mhz/1250mhz so this explain the temps going from 30'C to 40'C on idle.

This could be it. The memory is a full speed with flash, and the core is at 501MHz. Adobe, what are you doing? :/

 

[Techhog]

Anything I can do? or should I just deal with it since it's not really high enough to do damage and hope that Adobe fixes it at some point?

Turn off hardware acceleration for flash videos. It likely enabled it with the update, where as you had it turned off prior.

 

[KingFatty]

When you flashed the new video BIOS on the 7950, did you flash both settings (1 and 2) on the video card's BIOS switch? Maybe flip that switch and compare, see if things are any better between the two settings. If so, that's kind of inconvenient, but maybe open your case so you can easily flip the switch when going between mining or video watching to save on excessive heat/fan? Or, if it's too much hassle messing with hardware and keeping the case open, maybe just run a utility to flash different BIOSes as needed.

He is talking about Adobe Flash videos, not flashing the bios. It's simply a difference of hardware acceleration, which shouldn't matter, but if he insists on keeping temps as low as possible, he can turn it off by right clicking a flash video and turning off hardware acceleration.

Heh oops, this whole time I thought he was talking about this flash:

I'm only concerned that constantly running at 45-50C will cause damage eventually

It won't, but if you really are worried, turn off hardware acceleration. Two monitors can do the same thing.

Hm, okay. Thanks guys.
