My Intel laptop temp is nearing 95 degrees most of the time when I perform complex analysis. I wonder, should I use laptop cooler?
There are several models, the classic pad, teh radiator vacuum style. Which is better?
Laptop Cooler: Do We Need Them? What's The Best Model?

I disagree with turning off hyper threading with it off you are making the CPU work more for the same result.
That is in a perfect world where every program is designed to evenly distribute the workload across all cores… yeah nah don't think so.
Especially games, even more so older games are notorious for only utilizing a single or only two cores for the entire game.My laptop has 4 cores @ 2.8 GHz, 8 threads (4 real cores + 4 "fake" cores) with ability to boost to 3.7 GHz per core.
Yeah, having 8 "cores" running at 3.7GHz is great…. for the first 10 minutes until it starts thermal-throttling to 2.8 GHz and then has to throttle even further to 1.6 GHz per core to lower the temps, then jumps back to 3.7GHz, overheats in a minute, throttles to 2.8Ghz, goes back to 3.7 for a few seconds and then goes back to 1.6 GHz etc.etc.etc. and all of this can happen in 1 minute!
This speed variance is absolutely horrible for games (or, like OP said, "complex analysis") as the performance is not consistent and results in random performance drops and FPS drops that drive you nuts!!! Especially with hyperthreading, because your CPU is being pushed to the limit by forcing each core to work as 2 cores and not letting cores work to their full potential.
So I found in my experience, it is better to have always consistent 2.8GHz @ 4 REAL cores during prolonged (4-6+ hours) gaming sessions, even during summer in Sydney, instead of that fake 8 "core" performance and thermal-throttling 3.7 GHz that is all over the place.
I am surprised there is not more awareness for laptop thermal-throttling, it is a big issue that everyone seems to ignore.
Hyper threading does not "force each core to work as 2 cores".
That is the most insane thing I've heard. You absolutely do not want to distribute load evenly across all 8 vcores. Your OS (unless you run something old) will know which vcores related to which physical processor. You want related tasks on the same physical core so your processor can optermise your instructions and reduce redundant ones before they hit it execute part. That's the point behind SMT.I never mentioned clock speed so your point about that is a straw man
OP said analysis not gaming another straw man.
95C is perfectly fine when you're at 100% sustained loads. Question is - how much throttling is happening, and will a cooler reduce this slightly?
If you wanna reduce those temps, perform the first comment.
I use laptop coolers. got one from ebay for 20 bucks (something like this). Defs keep the laptop cooler than if I had just elevated the laptop on some stilts.
Depends on how the air flows in your laptop. Reapplying thermal paste may decrease the temp quite significantly.
Depending on the laptop I would consider opening it up, cleaning the dust and replacing the thermal paste
I use an Ergostand III but mainly for the angle/elevation rather than the cooling benefits… but I'm pretty sure the cooling fans don't hurt?
Turn off Hyper-Threading, undervolt your laptop and put it on an angled stand (basically a laptop cooler without fans). That is the best you can do.
Also, if your budget allows it, keep the room air-conditioned on lower temps.
From my experience all those "hektik gaming" coolers only reduce temps by 2-3 degrees so they are pretty useless.
I have this angled stand from AliExpress and I believe it does 90% as well as any other cooling pad. THough, back in 2019 shipping for it was free, now they charging $8… lol
