Highest Safest Temperature for 7950?

post #1 of 24
Thread Starter 
Hi all,

I have been using MSI Afterburner to monitor my Sapphire 7950 Boost GPU Temperatures.
At idle, temps are around 35 Celsius (ambient room temp is around 27 Celsius)
At average gaming (not really intensive games), temps are around 50~60 Celsius
At gaming around 100% load, temps hover around 65~68 Celsius

What would be the highest safest temperature?

My case (mid-tower) isn't that great, I only have one 120 mm fan (exhaust) and a stock CPU cooler.

Can you guys recommend some fan curves for gaming? The card isn't loud (I can't hear the fans at 100% load, and I use headphones).
Would this fan curve be OK? http://prntscr.com/s7ddo

Are there any risks or effects on the fan/card's lifespan if the fan speed is relatively higher? (like I set it to 60~70% or more at 100% GPU load)

I just don't want to lower my card's lifespan by having it too hot when gaming.

Thanks for reading smile.gif Appreciate your time

within MSI AB, you can create custom fan profiles. i would have helped with that but doing the same from mobile with small screen isin't helpful. Although you could google it and see for a walkthrough.

Yeah I do know that, but I am not sure what kind of curve would be effective and efficient

if you don;t mind the noise, you could keep it at higher percentages once it hits say eg 40*C etc. I have mine at 30-40% for range of 20-30*C. but its all personal preferences. BTW, have you o/c it and if yes, have you stressed it with either Heaven or Furmark or 3D mark

I did OC it up to 1075 MHz on Core and Default (1250 MHz) on Memory and temps hit around 73 Celsius with Heaven, but now I am running at stock to set-up the fan curve first. The card can probably handle higher speeds on the core. And yeah, I really don't mind the noise (I am using headphones anyway so most of the time the game music/SFX will drown the noise)

generally try to keep core temps below 70c and VRM temps below 90c. you can set a custom fan profile like, below 40c - 30%, 50c - 40%, 60c- 50%, 70c - 70%, 80c - 90%. fan noise will be an issue with fan speed above 70%. os set something which is agreeable to you in terms of noise and safe in terms of temps.

with msi hd 7950 cards there are quite a few which come with improper TIM application at the factory. many users have cleaned it, reapplied TIM properly and found temps reduce by upto 10c.

How do I check VRM temp? Btw I am using Sapphire 7950 Boost, but is there a chance the TIM isn't applied properly? Thanks for the reply

Use gpu-z for vrm temp monitoring thumb.gif

Oh got it thanks smile.gif Btw are there any negative effects to the fan/card or any other parts by having my fan speed set high (like 70% at 100% GPU load)?

EDIT: I only see one "GPU Temperature" display in GPU-Z frown.gif From what I have read on other forums my card probably doesn't have a VRM temperature sensor

you can try hwinfo32 for VRM temps. you should be able to read VRM temps on your card as it uses a reference AMD PCB design. the dual x cooler is custom. there is no risk to your card if you set fan speed to go to 70%. as i told setup a custom fan profile.
