M4Pro MBP Temps during gaming

Bungaree.Chubbins said:
You’re welcome. The control of iStat Menu isn’t unlimited, Apple’s firmware does limit what it can do, and I’ve designed my fan speed curve around that. So often the fan doesn’t kick in until it is into the 80°s, so the fans start fast, and then settle. I don’t foresee any problem with this.

This is the truth. I adjust my fan speed because I want to, not because I need to. That was the exact compromise I wanted to make.

So you cannot go below Apple‘s SMC settings to avoid overheating? Correct?

I couldn’t say, I’ve never tried. I’ve made the fans more aggressive so they will run faster at lower temps.

I wouldn’t stress about it too much. Apple has thermal protections built in. If you can accidentally set fan speeds too slow, and it gets too hot, it will just lower clock speeds to keep within spec.

I’m currently doing a little experiment on my MBP right now - trying out local AI video generation. The workflow I have through ComfyUI is really too much for my MBP (the 24GB RAM is nowhere near enough), but it is crawling along doing something.

The temperature shows around 80C and the fans are running but, even in a quiet room, I cannot hear the fans at all. I’m sure if 80C was “too hot” for it, the fans would have ramped up to a much faster speed to get the temp down.

I won’t be doing this experiment again, but I’m letting it run its course to see if it’s capable of completing the task. I expect it to fail but, for now, I just wanted to post about the temp and fans.

So you're not changing the fan parameters and stick with Apple's?

Tried to set new fan levels through Istat Menus Version 7 but the app won't let me access any fan settings. I have the full paid version downloaded from their web site. Any idea?

I can’t answer for your gaming, but I’m often using LLMs and playing with image/video generation on my MacBook Pro (unbinned M4Pro) and, when I’m using them, the temperature is up at 91C and the fans are around 5,000RPM (as it is right now). It gets really quite hot when on my lap, and the battery doesn’t last long at all.

I don’t know if this is good or bad for the MBP, but I didn’t buy this machine to NOT use its power. That said, I’m am waiting on the new Studio if it ever gets released. Until then, the MBP is just going to have to handle it.

Hear you on the battery. Playing Baldur’s Gate III on Ultra settings gives me about 80 minutes of battery life.

Still, it beats the crap out of the 25-45 minutes I get from my gaming laptop.

This works nicely for me. Super quiet when things get a bit warm, but if they're getting hot, it won't let it get too hot. Nor does it make more noise than it needs to to keep things ok. I rarely see temps reach the high 80ºC range now.

Got it fixed. Used the download version. Created a fan curve similar to yours. A bit more aggressive for gaming. In regular use the Apple fan rules stay in place. Only during games I use the tweaked settings. Temps came down from 91 to mid 70s and low 80s. Way better! Appreciate your help! Thanx so much.

Glad you got it sorted!

M4 generation boosted clocks which is why they run much hotter. Especially with your M4 Pro, it's a beast.

My M4 Max does get warm but the fans are much more reasonable in comparison to my PC which sounded like a jet engine in idle/basic use... Not to mention the PC puts out way more heat and is 6-7x slower than my M4 Max MBP so... letting that sink in.

Only time I heard fans and high temps were standard preview rendering in LR and some DaVinci Resolve && very few/some exports. but otherwise I don't hear them often.

running stock apple fan settings I cannot be bothered altering it to what works. Also I use automatic mode and occasionally drop into low power mode for the lolz when not doing insane stuff

Alte you gaming with it? Cause during regular workloads Aplle’s fan settings are totally fine.
