tripper1000:

Lots of good advice above. At the risk of asking a dumb question are you blocking the underside vents inadvertantly? What surface are you resting the laptop on? (are you playing on a hard surface like a table top, or something soft and squishy like a table cloth, bed, carpet or your lap?). Have the laptops little rubber feet come off, so it doesn't have good airflow anymore?

I ask because I've have seen the same behaviour (different apps) where a laptop consistently failed on the same app, but not for me, and it turned out that the owners useage habbits meant they blocked the vents when using that one app but not other apps.

Its on a table, but good question about the rubber feet. I'll look into that too.

Results are in.

Core 0 sits at 89'C

Core 1 sits at 77-79'C

Core 2 sits at 81'C

Core 3 sits at 70'C

Average temp reported to be 80'C So you are all probably on the money that its an overheating thing.

Is this while it's under load or just 'normal' operation ?

You’re just under 90C which is close but not quite the throttle range. Yes ideally you want 80C or below but if the cooling isn’t sufficient theres not much you can do unless you tweak usage to not use as much power. Caveat of course if you lose performance.

Do run something like hwmonitor or hwinfo to see what temperatures your GPU is going at while you game. The only other thing I can think of is possibly paging out of RAM, 8GB should be enough for something like TF2 but given Win10 plus any background apps can chew up to 4GB+ I wouldn’t be surprised if the stuttering is because it’s paging to disk, do you have an SSD?

If it is clogged up then you’ll need to open it up, clean and repaste the heatsinks to be sure your cooling is working okay. A few places can do this for you like you’ve mentioned PBTech or Computer Lounge.

my laptop sits at 92 degrees when under intense load and doesn't thermal throttle, it depends on the chip. 90-95 is still fine in some cases.

90c - 95c is not OK. That's almost TjMax.

TjMax is Maximum Junction Temperature - the point at which HTC (Hardware Thermal Control) shuts down the machine.

Intel & AMD documents repeatedly state that running CPU's over 75c for sustained periods deteriorates the chip.

How are you measuring the CPU temps?

Here's a CPUID shot of my Vishera.

Yea na its fine and has been like that since i had it.

TJ-Max is 100deg for this chip. it will only thermal throttle if the CPU and GPU are maxed. CPU only it doesn't thermal throttle when its at 100% by its self. Its starts to throttle at about 97 degs and wont go any higher.

I use core temp, HW monitor all seem to read about the same.

it all depends on the chip. 80deg it shouldn't be thermal throttling unless the OEM has done something funny. there is a big difference between cores though more than i would say is normal

If the OP would confirm whether those Temp's are under load or 'normal' it would assist this topic towards resolution.

How much disk space do you have free?

another thing that can happen is if you are running low on storage space on SSD this can also impact performance.

How much RAM/Memory usage do you have when gaming?

Im not familiar with the speccy software, but if you were using hwinfo64 that would give you all the CPU,GPU, disk, Memory info you need...

The latest revision of Intel's Thermal Management Engine (throttling) takes into account TDP as well as temperature.

When both GPU/CPU are loaded TDP is naturally higher, so throttling starts earlier. Either way throttling starts before TjMax.... (Tjunction = calculated die temp - TCase = heatspreader.)

Yes TjMax 100c is Intel's maximum and yes there are lower limits. Xeon E7 is all over the place seems dependent on core count & TDP.

The high limits are hard coded into the CPU.

Significant differences between core temps on Intel hardware indicates the HSF needs reseating. AMD always had one sensor so all cores read the same temp.

Not sure about Ryzen though.

I'm behind the times tbh. I haven't kept up with CPU or GPU microarchitecture chamnges since Haswell. I hope that's not a sign I'm getting old.

Btw 80c could also be Tcase (older architectures like C2D measured Tcase) which I believe is around 20c lower than Tjunction.

It will throttle when the bios says so. Could be any reason at any time.

Once it throttles the temps will look low because it is throttling.
