Kingpin Cooling KPx High Performance Thermal Compound 30G.

Very happy with this purchase. Paying this much for thermal paste is very much a worthwhile investment.It's helped me to tame the 4090 with a 20-22c delta whilst pulling 430-450w. It is far more viscous than I thought it would be which made spreading it easier.It's only been 4 days and I've come across a a Youtube video of how this stuff doesn't perform well after 6 months. So if this is the case, I'll update my review but if this remains unedited, assume all is well and that I recommend this thermal paste.Edit - 5 Months laterBy delta I mean liquid delta, ambient room delta would be nice though. Temps are about the same. Taking the average from HWiNFO64 and the water temps after 30 min where I sat in CP 2077 in a spot that is very GPU heavy and draws 410-440w. Simulated it all the same way as much as I could, CP 2077 has been updated a few times over the last 5 months but the power draw was pretty much the same and the taxing of the GPU which seemed to be similar and the delta was 22c. Whether it's due to how I or they applied the thermal paste, whether they got a bad batch or if it's due to them possibly living in a dryer climate (I'm in the UK), The GPU has gone as high as 530W for a few seconds, had a lot of high and low temperatures through different games and different parts of the map, multiple 3DMark tests, times when I have just relaxed after a long day/week/month and consumed YouTube whilst browsing Amazon, FB, Etc, so the thermal paste has certainly been through a lot of different and in some cases rapid temperature changes in these last 5 months. Not sure why someone else's results would differ so wildly but I am thankful that I never had to experience what some few others have.
