I'm currently using a -.144 core/cache undervolt, -.050igpu. While gaming, I cap my turbos at 4.0, 3.8, and 3.7 with 4, 5, and 6 cores active. With ambient temps around 70f my PUBG temps stay at about 80-88c on the cpu, 75-83c on the gpu. This is with gaming mode active and auto fans. I've also "overclocked" the gpu via nvidia settings and get about 1650-1850 mhz in gaming mode. With ambient temps 80f and above, I have to cap my 6 core boost to 3.4 to stay in the 80c range on the cpu. While browsing the web in 70ish F ambient, the temps hang at around 47-52c on the cpu.
I've read a lot of competing info regarding Kryonaut and MX-4. People warn of pump out with heatsinks that don't make flat and tight contact with the die. The vapor chamber design seems to not be ideal for these compounds. Kryo also seems vulnerable to pump out under frequent >80c temps. I do not want to have to replace my paste frequently, maybe every couple of years at best... I also haven't seen a lot of of data clearly showing good results with repastes. 3-5c doesn't seem worth the trouble as the real world benefit would be +100-200mhz which is maybe 3-5 FPS in game...
There's also the fujipoly pads, but super expensive... If I was going to spend the time and money to do a repaste and repad, I would want to see a 7c-10c drop, AND not have to repaste anytime soon...
I should add that without the throttlestop tweaks, my cpu spikes to 100c at max boost (3.9) and throttles itself down during heavy load. With the settings, I can game comfortably with okay temps. Should I RMA, repaste/repad, or just enjoy it with the undervolt settings?
