Hello guys i have a little problem , look at the vrm temps , do you see something out of the ordinary? Its a Gigabyte 7870 hz oc ed 2gb . I sold my old gpu and it worked perfectly no problems what so ever and after the gpu arrived to the guy he said (after a few hours) that his vrm temps are 127 and that he cant play games on it. Can you please help? i will offer any info you need . I know i sold i working card , a hour before sending it i was playing bf4 on it .
127C is stupid-hot; the GPU should be throttling, and possibly even shutting down.
Anything beyond 105C is a definite red danger zone for a lot of components, especially transistors and capacitors. The PCB has higher tolerences, but that is just the board itself, not the components.
When you owned it, did you check ever check the VRM temperatures?
That's really strange, I'm pretty sure the VRM 1 + 2 should be the same on a 7870 (I think its the same sensor maybe with dual connect).
It's probably a false result. Did you try playing a game with the case open?
At 127 you should be able to feel the heat radiating from the VRM sink. If not touch it with an Alan Key (don't touch anything else). If it becomes too hot you have a problem.
Over 100 you can normally feel the heat from the back of the card, not warmth, but actual heat.
To fix it - take the card to bits, press the plastic junctions together that hold the VRM in place, then seat the sink properly. I add TIM to the VRM, it drops temps alot. Make sure to use non conductive, it takes a bit of experience to not make a mess.
If its still high buy a new card (or replace the broken regulators if your a genius).
I thought about the fact that the temps should be almost the same (the thing is that i sent him the card and he "says that its broken" even though i had no problem with it). When ill get the GPU back i will test is in game open case all of it . Thanks for the info :D.
The temperatures do not, by necessity, have to be the same. My XFX R9 280X has two VRM temperature sensors, and they give different read-outs as well (albeit, less than 10C difference.) Ditto with my Asus 990FX Sabertooth R2.0 mobo.
But, yeah, like you already have planned, give it a thorough testing and gather all the data you can. Then try replacing the cooling solution on the VRM, see if you get different results. As @Tastyrabbit said, it may be a bad reading, or faulty sensor.
