Just added an ASUS DCMOC GTX 970 (mini) next to an MSI GTX 970 , and
did some stress test under nominal clock speeds using Hwinfo64.
I got that the MSI GTX (which has been crunching for little more than one year), raises temperature much faster than the ASUS.
Both monitors are attached to the new ASUS which lowered MSI temp by ~ 10°.
Current situation is as follows:

MSI:
from 33 to 55 °C in 4 seconds (+5.5°C / s)
reaches 75 °C in 180 seconds
ASUS:
from 26 to 35 °C in 4 seconds (+2.25°C / s)
reaches 62 °C in 180 seconds.
Right now i am forced to underclock the MSI core by 500MHz (from 1114MHz to 612MHz) to keep temp ~ 71° in full winter with the case open...
voltage can't be lowered with MSI, and remains at 1.187V (unfortunately), whereas the ASUS keeps cool at full speed (1089 MHz) with Vcore=1.212V.
The MSI is closer to the CPU (higher) and the ASUS is lower, both fans are blowing upwards, but the ASUS being shorter only 'blocks' the flow on one of the two MSI fans.. More in detail:
ATX motherboard (ASUSM5A99x):
- MSI is mounted in PCI-express-16 slot 1
- ASUS is mounted in PCI-express-16 slot 2
This leaves about 2 cm between the boards.
Do you think that this indicates a problem in my thermal paste / heat sink seating of the MSI GTX 970 ? Also if i lift the MSI card by a few mm i see the temperature sensor jumping from 75 to 90° in no time, and if i release the MSI card to its original position (it is a little bent due to the weight) then it goes immediately back to 75°... weird..
Any comment is much appreciated!
Thanks
