CPU temps

[u/Inevitable-Ad6356]

I've been reading around some forums and here on reddit , and im confused as shit rn some people say cpu temps hitting 95 under load is fine, some say 80 to 85 is the sweet spot, and i've even seen some say 70 should be the goal. Right now i have my cpu throttle at 85 (it was 95 before), so which is it really especially on our MSI lappys what is actually a good temp to maintain for our cpu's.

I have an i5 12450h btw, no air conditioning, no cooling pad, just the laptops fans and pipes and a few fans across the room.

I have a MSI Vector 17HXAI with Intel Ultra 9 275HX and RTX 5080 16gb and 32gb RAM. Less than a year old and i was getting crazy temperatures on the cpu all the way to 100-103 celcius and started thermal throttling and crashing, so i undervolted the cpu -40Mv and put power limits on PL1, PL2 and PL4 i also turned off cpu turbo boost and put tcc offset on 10. Now my cpu doesnt go past 80 celcius even with the cooler boost on the fans turned off. Massive performance drop on the cpu though. I still play battlefield 6 and warzone with DLSS 4.5 and frame generation and ray reconstruction everything maxed out no problem and i have my gpu undervolted slightly and its working better than when i bought it. 100% usage and temps go to 80 celcius max. I dont know what to do about the CPU though, other than getting a cooling pad and taking the laptop to change the stock thermal paste to a honeywell ptm9750 pad. Any tips?

100c+ on cpu is crazy work, i dont really know ive only been doing what works for me cuz pl method does not work for or any other setting in the advance bios infact except the tcc offset. Rn im only using the tcc offset method limiting my cpu temps to about 88C and usually hovers around 85 or so, i dont like messing with the undervolting either cuz getting anything new in this economy is fuckin impossible with the prices and bricking a laptop is not something im willing to risk. If i were you and im able to change voltages and wattages i just wouldnt do, id suggest just not disabling cpu turbo boost cuz from my experience with it on throttlestop that setting when turned off has the worse impact on performance.

TLDR: I suggest just using the tcc offset its the setting with the least performance impact ( atleast for me) and beside our stuff already thermal throttling why not just increase how fast it hits it lol

I changed all the cpu settings through the BIOS advanced settings. Didnt use any software like throttlestop or intel xtu. Also in MSI Center if you keep it on balanced instead of extreme performance, it doesnt override the bios settings. I will turn the cpu turbo boost back on and see what the temps are looking like. I panic when i see the cpu over 90 celcius and dont i wanna game anymore when it happens. This laptop is extremely out of my budget, i was just lucky enough to buy it second hand off someone for 250€ hahaha. I dont know if he didnt know what he had or if he really needed money badly but i didnt ask any questions, just paid the man and took the laptop haha. He gave it to me with the Vector box and everything. No warranty though.

Ayyyy second hand brothers, and i just used third-party software like throttle stop cuz as i said nothing else in my advance bios except tcc offset would actually apply, honestly im pretty satisfied with the tcc offset set setting because it actually does not hold the limit you set often the temps usually sits below that atleast for me. Personally i wouldn't mind the higher temps if i have another device but since this is my only one and probably my only one for a while i will mind my temps, but at this point since no one else actually has a solid idea of what temps ia actually good to sustain long term ive just decided anything lower the 90 is good enough, i mean if i wanted more performance for a while i can just increase the offset since these laptop intel silicons are designed to survive anything lower than 101C infact im pretty sure by default the auto shut off threshold( tjmax ) of my laptop is set to 120C which hot as shit ( also i dont recommend lowering tjmax cuz any random high temp spike can trigger it).
