Asus K53SV heavy mods - advices needed

Hi guys! I have a pretty old but still capable for some emulation Asus K53SV.

Because of the lockdown I have recently upgraded from an i7 2630qm to an i7 2860qm. A nice bump.

Anyway, it runs HOT. It has always been hot but now it's hotter! Aida64 takes it around 90-92 degrees C with no throttleing. But it's ways too much.

My initial thoughts were to build a custom enclosure to put in the mobo and an e-gpu, but then I thought it would have been too much of a hassle because of the too old and slow mini pcie slot. Not totally worth the effort. Also: Buying an sff optiplex would cost me less, in the end.

So my next thought was: let's build a custom enclosure for just the motherboard with a couple of additional fans powered from the m-sata slot with some adapters and regulators bought on Aliexpress.

Then I came here and read about bad dye-heatsink fits. That might be the cause because when I unmount the heatsink I have quite a lot of thermal paste left on the dye. Another hint: thermal grizzly does not give me more cooling performance over and old tube of MX-2 (TWO...).

So what would you advice me to do? Open case+cooling or to keep it simpler just put a thin layer of copper with some thermal adhesive between the dye and the heatsink?

If I should adopt the custom enclosure route, would it be enough to stick one of those alluminum heatsinks (wide with some fins, you can easily and cheaply find them on aliexpress) over the heatpipes with some thermal glue and adding an additional fan?

I obviously have high temps on the GPU (gt540m) as well.

Anyway, the simpler the better.

I'm in your hands, pros and if you could kindly provide some Aliexpress links it would be awesome

Thanks

 

Grab a new heatsink from eBay, also, just removing the motherboard from the chassis and running it bare/on open air will make the temps drop A LOT, try it and see.

I have ran a Asus GL771JW(i7-4720HQ and 860m) motherboard with only its original heatsink, bare it will run at 62-65ºC, on the chassis, high 80sºC, a grill pattern drilled under the fan put it around 70-75ºC under load, but a chassis makes a lot of difference in the air flow, you can do the same on your chassis, it will help temps drop a bit, also, removing the keyboard will allow the fan to intake more air.

 

A new notebook heatsink or a small desktop heatsink with 4 holes drilled in? It has to be really small: 6x6cm and it will be VERY close to the mosfets (I can assume).

I have read a thread here of a guy that says that putting a thin copper layer between the dye and the heatsink helps a lot. I might think that after almost 10 years the original heatsink does not make proper contact anymore.

Do you also think I should UNDERVOLT both the cpu and the gpu, if possible?

I might remove the DVD drive as well. Nobody uses it anymore. Unfortunately all those blower fans dvd replacements for laptops are not available anymore. That would have been a clean solution.

 

A new heatsink for your laptop, it shouldn't be running that hot, are you sure your heatsink fins are properly cleaned?

You heatsink might be warped from factory, because it should be making good contact, there should be a very minimal layer of paste when you remove it.


A custom heatsink needs to be machined so it sits nice and square and doesn't break the die when you screw it down, and you still need to cool the dGPU, not sure if you can undervolt the 3rd gen CPU's, try with ThrottleStop, the dGPU doesn't seem to need an undervolt, because you are running an external GPU.

Drilling your chassis under the fan will help a lot more than any DVD fan blower will ever do.
