Yup Honeywell TPM7950 is pretty awesome.

No problem. When you run the test make sure you minimize the window that shows the donut. Power will go off the chart then. 😁

Wow yeah it shot to max power (450W in my case, didn't have the power slider past 100).  Looks like I might need to re-paste and/or check my mounting or I just have a hotter hot spot.  GPU/HS temp was maxed at 59.4/73.5 with a water temp of 35C.  HS temp should be a couple degrees cooler than that I think.  Could just be my card I guess but pretty sure other stress tests I ran a year ago the HS was closer to about a 10C difference.

If you decide to re-paste definitely try out some PTM7950.

I ran the test at 450w and got 56c max on the gpu with the hotspot at 64.8c which is crazy as I'm just using the stock cooler.

you had me worried but apparently im not gaming enough to dry out my paste... def using the honeywell when its time tho. 

Yeah, I was getting a bit worried myself as I didn’t want to rma. Glad the honeywell worked as well as it did. 👍

I cannot see which 4090 you have, on my TUF 4090 the core and memory are fine, but hotspot-core ("Delta") gradually increases over time to around 20c. I recently applied fresh paste, and hotspot-core delta was <10c. Then a week later it increased to ~15c, and I guess by the end of April it'll get to that 90c zone again. It happened with two high quality pastes (Noctua NH-T2, Thermal Grizzly Kryonaut Extreme). 
I'm not sure what can be done to solve it. I guess it's a mounting pressure issue, in which case changing to softer thermal pads could help, I'm also interested in testing the PTM7950. Doing monthly repasting is not a good idea, the card is way more likely to break due to the ****ty connector than due to high hotspot. I also haven't tried undervolting.

Get yourself an Authentic Honeywell PTM7950 from MODDIY, I suggest the 80x80 pad that's at least 1x gpu and 1-2 cpu's. The things are amazing on cpu's and gpus.

I have the gigabyte gaming oc. PTM7950 will fix your issue. It did for me.

That looks like some good stuff
