Nice! I saw about ~4C lower temps using the coolermaster paste than came with my hyper 212 CPU heatsink.

Compared to my old EVGA GTX 960 SSC 2GB card the system is pulling about 25 more watts under load (reading from my killawatt).

ASRock Z97M Pro4/ i7 4790K @ stock/ 32GB DDR3 1600/ 480 GB SSD/3TB WD for storage

5/31/2015 - 960 GTX SSC - OCZ 500 watt PSU from 2006ish

55 watts on desktop

171 watts on prime95

235 max watts on 3DMark11

205 watts average on FC4 (215 max)


7/3/2016 - XFX RX 480 4GB stock - EVGA 750 watt gold PSU from 2016 (another 8x2 RAM kit to total 32GB)

54 watts on desktop

173 watts on prime95 (max heat)

260 max watts on 3DMark11

230 watts average on FC4 (250 max)

338 watts Furmark plus prime95 (max heat)

The first thing I did after some initial testing was repaste with some Gelid Extreme. Dropped the temps considerably. Don't know exactly how much, though. Never gets over 65 while gaming.

I would like to report that using wattman to lower the voltage in stage 6 and 7 (set to stage 5 mV) my 3DMark11 score went from 14878 to 15090.

Also, my killawatt measured about 20 watts less usage during the 3DMark11 run.

Do you know if that is the standard spacing? I'm interested to know if my nzxt Kraken will fit one of these cards.
