• RED = Thermal Grizzly Carbonaut
  • GREEN = PTM 7950 (no idea if the original or some fake but it works, bought from random seller on Aliexpress)
  • before Arctic MX-4 was hitting TJmax 110C at 312W (good temps comparable to Carbonaut for first few days after application then drastic increase in short time due to pumpout issue)
  • stock paste was hitting TJmax 110C at 255W (when I got the card it was used and already almost 2y old)

Unfortunately I don’t have any data for the MX-4 and stock paste to put in the graph.

Testing was done with TimeSpy GPU Test 2 on a loop for 10 loops.

    Well, I’ve tried some big OC and shoved 400W into the GPU and the PTM is still managing it even on air cooling. (Not reaching actual 400W because of hitting TDC limits in this test and I didn’t capture again after increasing TDC but just add 2-3C to the blue graph). This is without side panel and at 100% fan speed obviously.

      Super impressive, honestly, but I’m not surprised with Thermal Grizzly. I can’t tell from the images, but did you use the pad for the VRMs and Caps, too?
