ASUS GL502VT Thermals

Hi, I've tweaked the voltage of the CPU which originally used to run at 88c now down to 78c but was looking to repaste the CPU and gpu. The videos I have seen have paste or white stuff on chips around the CPU/gpu. I just wanted to double check what these are and presume they would need new paste.

Honestly, 78*C is a very solid result and I'd say repasting is not needed in your case. You could if you wanted to but I doubt you'd see any real benefit at the moment.

 

I thought that but then after watching a YouTube video it looked like it was applied so heavy that it wasn't as effective as it could be.

It was you who helped me decide on this laptop and so far very pleased. I do get some random lag on PUGB but that's a bug I think with the turbo boost.

What temps are you currently getting? Also I was going to upgrade the ssd, any recommendations does it support NVMe?

Yes, the M.2 slot supports NVMe drives. Mine came with a Samsung SM951

As for thermals - I've been using it for a year and currently my load temps are around 85*C in demanding games. Though I am on BIOS 203 aka the quiet profile for the fans.

As for paste - having more than needed is better than having less - I would honestly say 78*C is perfectly fine. It won't affect anything if you go lower besides maybe surface temps.

As for PUBG - that's the horrible game optimization, not the hardware.

 

On the subject of thermal paste... having more than needed is NOT a good idea as the efficiency of heat transfer goes down the drain at that point.

You already dropped the CPU temperature by about 10 degrees C from lowering the voltage alone.
That's an excellent result for undervolting.
Right now, you should be fine in terms of temperatures and don't think a re-paste is actually required.

However if you are outside the warranty period and if you think its warranted, then re-pasting should be relatively easy (provided Asus made access to the GPU and CPU relatively easy - not necessitating a disassembly that is).

If you decide to repaste the CPU and GPU, I suggest you use GeLid GC extreme thermal paste.
Its' one of the best non-conductive thermal pastes that works really well.

Chips around the CPU and GPU that have thermal paste on them could (and I repeat COULD) be voltage regulators (I'm not sure if they are though).
For those (VRM's is I think the correct abbreviation), light application of GeLid GC extreme thermal paste should do the trick, however, some people have used thermal pads instead like Fujipoly ultra Extreme XR-m (thermal conductivity of 17.0 W/mk).

When applying thermal paste, I take it you already know of the grain of rice method and/or spreading a very thin layer of paste across the CPU and GPU dies.
For laptops, spreading the very thin layer of paste works well as the pressure from the heatsink is not as strong like in desktops).
