Intel i9-10850 hot

[Petrolhead]

I recently built a pc using an intel i9-10850. All was fine, idle about 32deg, room temp 20deg. On load ie Cinebench it was 88deg

The cpu is cooled with a Fractal Design Celcius 360

today i decided to Replace the fans and do some general tidying so removed the block from the cpu.

once done fired the pc back up, idle 50deg, hmm thats not right so i removed the block a reseated it.

refired the pc, idle 40deg but as soon as i ran cinebench it went straight to 100deg! and crashed

so i removed the block again and took a couple of photos for you to look at. One thing idid notice, both times i removed the hold down screws there seemed to be not much resistance/spring.

its as though the cooler block is not seating properly

any thoughts

edit: i should ad the the cpu is running 5ghz all cores

Update

i have a spare Corsair H110 Gt so rigged that up, very crude, just clagged it onto cpu using what paster was on the gpu and the rad and one fan sitting next to the case.

idle 28deg and 88deg when running Cinebench

so is the Fractal buggered?

Those temperatures are still high if you are stock.

Have you checked what your voltage is? It seems the majority of motherboards overvolt the 10 series chips when left on auto. Also is multicore enhancement enabled?

Should have said its running all cores 5ghz.

re your other question would need to check but 1.29v comes to mind. Re multicore enhancement, cant remember, i assume i would need to check the bios?

 

[Petrolhead]

Are you using new thermal paste? You need to clean off the old stuff and use new paste every time you remove the cooler.

Yes except when testing my old cooler, see post 2

It would definitely be worth double checking the voltage. Also your LLC as any of these settings set to auto tend to push way too much voltage than required.

Multicore enhancement is also worth disabling. It will allow all cores to use the max turbo profile, but in reality this just results in significantly more heat.

Apart from that to isolate if there is a cooler problem I would revert the overclock back to stock settings and see how the coolers perform. It could be that after checking the above, neither can quite handle a 5ghz all core. Really your max load temperatures with realbench or similar need to be below 85c.

Thanks

i would agree apart from the fact that its been running the OC for a month with not problems plus the other cooler runs fine

 

[Petrolhead]

Yes

i seem to have sorted it, at the 5ghz oc its idling at 33deg and when running Cinebench 88deg. I cleaned everything and reseated the cooler but turned it 90deg

to be honest i am new to overclocking and got my setting from a youtube video by Boosted Media and another site, which i cant remember.

maybe i should start a new thread and ask there about overclocking as according the HWinfo the vcore is running at 1.32v

Top, exhausting out

Well i thought it was sorted but it started playing up again, so i put the bios back to default however 40-45deg idle and when running Cinebenck 100deg!

I remembered that on the Fractal AIO you can switch between Auto and PWM. It was on Auto. So I switched to PWM. Idle 30 and when running Cinebench 60.

so thereis obviously somit up with Auto mode.

going to run Cinebench on a loop for a while and see how it goes.

i also think will just leave the CPU std

Maybe something bad happened to the AIO Pump? I had similiar problem and it turned up as broken pump.

Possible, only bought it 1st sept

Originally DIY people used car radiators, or cabin heater cores with genuinely extreme amount of heat dissipating power.
And when designed for PC cooling radiators originally appeared those used to be like 5cm thick.
But when waterpipe coolers become fashion pushed for everyone and their pet dog, people didn't want to that big things into their case.
So marketers shrinked radiators to slim ones.
At the same time shrinking also heat dissipating power.

interesting and valid

i have just finished a water loop for the GPU (RTX 3090) using a EK PE 360 rad which is keeping the gpu nice and cool.

i have been wondering about, what if i added the cpu to the loop. Another 360 rad maybe thicker?

tried lapping the CPU down 1mm and put 1mm shim on the holding down bracket of the CPU block?

failing that delid

So giving an extra 2mm clamping force
