Recently got the Predator PH18-72, cpu temps on the i9 are reaching 80c even when task manager shows usage between 1 and 7% and just idling on the desktop. Fans are working fine . I played No man's Sky on a balanced power profile just walking round a planet and temps reached 100c after just 5 minutes on some performance cores.
I found by disabling the igpu and just using dedicated 4080rtx the temps on the cpu stayed around 86c.
I watched a video review of someone benchmarking games on the lenovo i7 Pro with the same cpu and the temps seemed similar.
Is this normal behaviour? I see individual cores going to 90c just for a few seconds when just on desktop idling.
I've come from an ancient i7 ivy Bridge laptop by asus that has keep me going for 10 years and didn't see this behaviour, though the speed on the 6 cores topped of at 3.4ghz if pushed

It’s highly likely that due to the size of new laptops they have a shared heatpipe cooling configuration. This causes one or the other to run hotter even at default stocks and idle.
 
I have the PHN-18

Mines the i7-14700HX, and gets pretty warm doing desktop stuff, when gaming it stays below 90c as the fans kick in hard.

These CPU's are just VERY WARM, and unfortunately, ACER refuse to create a BIOS that allows undervoltage.
 
First thing to do when getting a powerful laptop is to throw all your expectations of PC CPU operating temperatures out the window. So long as it's within the manufacturers specs of the operating temperatures, you're good to go.

If you don't have the access to voltage changes on the CPU, then all you can try and do is ramp fans to ensure minimal throttling.
 
Perfectly normal on these @Ugly in fact yours is on the low side in laptop chassis namely because the predator has good cooling.

Only an issue if significantly thermal throttling or crashing/freezing but on the last few generations expect 80+ to high 90s+ in easy task and then some in gaming.

Heat dissipates rapidly through the cooling solutions though so whilst the laptop will get hot in places it won't damage anything.

Gone are the days of low idle core temps core temp unless you are using lower power ultra portables which the ph18 is definitely not.

Can you undervolt in windows? I guess if you did you'd have to do it on every re boot
 
Thanks for the replies..Guess I've been used to my 10 year old asus with ivy Bridge. That laptop was top tier when I got it- ssd, 980m gtx, 32gb ram...it can even run cyberpunk 1080p on low to medium settings between 40 to 50fps.

Nope. Fully locked down. Even intels own software reports it's locked down.

Needs Acer to do a bios revision that allows the cpu to be unlocked.

I'm still in my return period and I could get a lenovo 7i Pro with same spec for roughly the same price apart from it having a 16 inch screen vs the acer 18 inch. Maybe I should return it?

Depends on what you value more.
The better screen, or a quieter cooler running CPU.

Mine came with a 3 year warranty according to OCUK... so I'm ignoring the locked cpu
