Simple and very effective cooling "mod" for p775dm2/p775dm3

No luck with p750dmg also I broke some clips in my keyboard when I try to find my bad speakers. I tried on gpu, my heatsink is different, I cant use stick for cpu. Can I use p775dm3 heatsink in mine?

 

Dont you think a copper shim would eventually o better the this? I mean it copper, an could conduct heat better!

But also have to add another layer of thermal pads to vrms tho!

 

With use of copper shim you will need a extra layer with thermal paste

 

Yes, unless you solder the shim to the heat sink, an extra layer of thermal paste is needed. It might be better than stock if the fit is horrible, but if the stock fit is good it might not work as well as stock.

 

Okay, one thing i didn't understand, why would i need an extra layer of thermal grease? The shim is supposed to decrease the distance between the chip and heatsink, how would it need more thermal comp then stock heatsink!?

 

If you do not put thermal paste on both sides of the shim (or solder the shim to the heat sink, which would be ideal,) and assembled it dry then you would not get adequate heat transfer from the CPU to shim, or the shim to the heat sink. You would need thermal paste on both sides of the shim for exactly the same reason you need thermal paste without the shim.

 

Die-paste-shim-paste-Heatsink.

Edit. @Mr. Fox damn fast

 

Indeed so a shim is only used when the gap would make a thick layer of paste which is worse at conducting than metal by more than having extra thermal interfaces.

 

Thats why after reading @Mr. Fox 's advice, i straight away ordered a capable solderer to get my shim permanently on the HS

 

Or just buy the thicker SL Bitspower IHS if you have Kaby/Skylake.

 

I dont live in usa, so, i dont think that would be a good idea, and since also i have a coffee lake, so, i dont think that would work.

 

Yeah, You need one for Coffee. Another one, but for Coffee.

 

Wow! Amazing copper IHS. Do you see any improvement over the stock one?

 

The stock IHS is nickel plated copper by the way.

 

Same with the Bitspower lid

 

Posting here because I'd like to know if it's possible to simply unscrew the heatsink while leaving it in place and sliding the paperclip or do I have to remove it completly?

Thanks!

 

It is much easier to just remove it and do the mod.

 

Well I tried this mod and for me it didn't do anything unfortunately, GPU 75c load Before, 75c load after. I guess it was as good as it gets already.

But I couldn't do it as well either, the heatpipes are welded/soldered whatever so far to one side that it's not really very possible to lay the paper clips from one side to the other, did it more like a C shapre in each side. Maybe that didn't give as much support. Under one of the spring arms it wasn't even possible to put any paperclip

Tried to put some small wooden sticks under the CPU arms that did nothing either. Well actually it's hotter than after the first time I delided the CPU, but I don't think that's because of this. The CPU has just gotten a bit hotter over the past year for some reason. Well a couple of more years and this laptop will be completely outdated anyway. 6700K :/ kinda outdated already.

 

a great mod,so simple but very effective, i did not know there was a lack of pressure to the cpu and gpu plates i have a 775 so may well try this, did you see a temp improvement ?
very clever though,thanks.

 

Check whether there's still sufficient liquid metal under the lid, it may have moved or soaked into the IHS

 

Has anyone tried this with the P775TM and gtx 1080? Did it help to lower the gpu temp from 85-88C?

 

i will try this mod tomorrow and let you know my findings. P775TM1 with 1080 LM on it

 

It worked on my P775TM1 G with my 1080 lowered my temps by 14C! after an overclock and undervolt and this simple mod.

 

I tried on P750DM-G results was not magnificent but I tried LM on GPU and for delid I did not get -20 C like everyone got but now GPU cooler like 5 C and it is enough for me because my GPU was hitting 75 C, 78 is black screen now its 69~70 C and its lowest I ever got. I could not best pressure with paper clips because my hand works sucks but I could better than last time one year ago. I must try washer too and when I screwing I pressured with my hand it is very important too like sager guy said. Thank you Sager guy and thank you OP for simple awesome mod.

 

Usually adding LM and getting higher temps means the contact is not flat and close enough.

 

I removed the back cover too and temperatures now max 70 C with +125/200 12mV GPU and max 83 C CPU. I got the 1mm arctic pad yesterday but I searched it must be at least 1.5 mm for VRAM maybe I try with 4 paper clips mod like on 1070 sli mod with it when it get hot weirdly one day. Kryonaut is good but just for three days. LM is savior.

I used paste on pads and teared when I relocate them and kryonaut dried again.

Is it okay P370S code for p750dm-g? It could not stand alive on 78 C and up since day one.

 

Do the P750TM1-G laptops have limited heat sink pressure too? Would this mod work for me?

 

That depends on the paste spread pattern. Post up a pic if you are unsure what it's telling you.
