I may have spoken too soon i'm seeing lower hotspot temps in games and benchmarks Its only AIDA gpu stress test has has it going much higher.
Are 96ºC on the memory, normal for that card ?

My ptm7950 sheet had amazing results on 4090 for about 6 months - the hot spot temps started creeping back up to 100C and there was a bald spot when I took it apart.

it does ultimately pump out - replaced with kryosheet and that worked extremely well - has been on there with no issues for about 6 months and no change in temps.

I wonder how thick they make them because I may try them on my Dell XPS Gen 1 laptop for the chipset and gpu

theyre pretty thick and actually easy to put on - so I think as long as your cooler / chip contact doesnt have any defects it's probably fine. It does take a few runs to settle in though the initial performance is pretty terrible.

Still overall I would say if pump out is your worry just use a kryosheet and never have to think about it again.

PTM7950 AFAIK is what nvidia uses as OEM on their FE cards which is why I swapped it with the same initially.

Just a little update on PTM 7950 long term results with my 4070 Ti TUF card temps were 10-11C delta between core and hotspot for the first 4-5 months, 7 months later now it's 13-15C delta, guess this stuff degrades after serveral months.

I am using a Thermalright Heilos pad, its ok still, been a few months. MSFS kicks the hotspot up to 80, no matter what I do. Its still better than what was there before.

Also, that is +150 on the core for a bit over 3GHz, +1500 on the mems.
