Clevo p775Dm3 with 7700K high CPU temperature

Hi everyone,
I recently bought a P775DM3 with an ES 7700K that runs at 4.2Ghz @ -100mV.
Still temperatures are quite high on full load (War Thunder session or benchmarks), about 84°C.
The GPU, a 1070 GTX, runs quite cool though, at about 65°C, thanks to the paperclip mod.
I did the same for the CPU fixes on the heatsink but no joy...
Should I delid the CPU to lower the temperature or is 85° ish OK?
Thanks

 

everything below 90C is fine for longer periods of time. how was the paste job? even and thin layer covering the whole cpu ihs? what thermal paste are you using?

 

A delid will get you a higher frequency, it depends if that is worth it for you.

 

It is definately high... 1st definately go for delid, 2nd definately go for "good" bios, which allow the fans spin upto 100%. Otherwise the fans max at 80%. My 7700k runs 4,6ghz@1,21V and under full 100% gaming along with 100%gpu 82C.

 

Thanks for the answers. For now I only have the stock bios so FAN is maxed out at 80%.
I used MX4 thermal paste on CPU and GPU. The paste job was done OK I guess with a thin layer.
I'm able to run my 7700k @ 4.2Ghz and at -100mv, which is not too shabby. But if I could gain 20°C by delidding the CPU,then it's definitely worth it IMO

 

But is it safe to delid the CPU and how would you do that?
Should I buy a delid machine or do that the old fashioned way with a cutter?

 

I have delided every single cpu I had... its totally safe, but find an expert who makes it for peanut... it will be resulted in -15/-20 degree... totally worth it. After delid you will have lower temps at higher clocks... you can hit 4,5ghz easily w/ 80C....

ps: i have just sold my belowed 775dm3

 

i dont recommend the "good old" methods via cutter/razorblade or vice, best to get a tool like the delid die mate or rockit 88 tool kit. way safer, not really expensive and u can sell them off again if ure done

btw, MX4 is crap! switching to thermal grizzly kryonaut or GC Extreme will already get you like 5C lower temps

 

Ok thanks a lot mate for the piece of advice!

 

You certainly need a steady hand with a razor blade, one slip and bye bye CPU. Being crazy I did this myself on two chips but get the tool, your heart will thank you

 

That I will!
I'm definitely not risking my 7700K...

 

The tools used properly should be pretty safe though.

 

You can easily find some 3d printed delid tools for less than 10€ on ebay. I think I'll go for that.
Is it risky to use the CPU without lid? Do you think I could do that on my P775DM3? The way we used to do on SB or Haswell mobile CPUs...

 

ah no, the idea is to replace the thermal compound between ihs and cpu die with something higher performing than the stock intel goo. most of us go liquid metal. after that, its just a matter of slapping the ihs back on and using regular TIM between IHS and heatsink u can either choose to properly remove the glue between ihs and cpu package for a tighter fit (cpu clamp holding down ihs) or gluing it back on again (easier handling of the cpu itself).

 

I don't think you'd damage anything physically or electrically, but thermals might suffer without the IHS/lid, consequently doing damage if things got too hot.

 

I don't get it... The mobile CPUs are all delid, aren't they? I think the cooling should be much more efficient without the IHS as the contact is direct between CPU core and the HS. But maybe you're right, as the contact area of a delid CPU is obviously smaller than with the lid on...

 

Mobile CPUs have the heatsink measured to fit and they don't have a socket so the PCB wont be bent, a socket is not in the way of the heatsink making contact and there are no pins to worry about making contact.

 

They're also mobile CPUs; TDP is quite a bit lower and there's typically less heat generated compared to an LGA chip.

 

Remember I7 920xm, 2920xm, 4930mx LGA chips... They had quite high TDPs for mobile CPUs, still lower than their desktop counterparts though. But overclocked, they easily reached 80W TDP, even more. I had a 920xm on a m15x R2 overclocked to 3.8Ghz with a vcore mod (metal pins on the socket holes directly ) and it pumped a lot of juice. And acted like a heater!!

 

those were the days... they dont make mobile cpus like that anymore... starting to miss my 2960XM

 

You bet! These were incredible CPUs...

 

It's the same silicon on a different socket. In the right conditions it could be just as hungry.

 

oh cmon meaker, of course its the same silicon on a different socket. thats not the point, were not talking "what ifs" but what IS. and today´s mobile CPUs are just crippled BGA and TDP wise

 

The non extreme editions were TDP locked too even with the socket. The extreme editions also cost more than an entire motherboard with soldered CPU and GPU can cost.

 

well, you had 1) unlocked bins for every cpu model (was it 3 bins?) 2) socketable cpus, so no problem swapping out/upgrading 3) higher tdp headroom with the extreme editions

and last but not least: one failed capacitor, mosfet, resistor, basically any important SMD and ure in for a whole motherboard (lets face it, whole laptop!) replacement nowadays...

Unlocked bins in the 3 and 4 series. Still power locked though.
