Decided to continue my previous post Offers and Wanted › WTB: Thermal Putty in Auckland here for anyone interested.

Bought some cheap TF7 off the vendor but it was really thick out of the syringe so ended up using some 5 year old unknown leftover coolermaster paste I found at home instead.

Finished CPU, GPU and VRM repasting:

Ran the laptop up and loaded into a Fortnite game, running at 70C ingame seems pretty sweet to me!:

I am very surprised that people on this forum think thermal putty is thermal paste lol.

Anyway I got Upsiren utp-8 and ptm7950 to repaste my gigabyte 3070 gaming oc.

Before:

After

Max hotspot and max temps are the most insane.

That and the core clocking higher whilst max temps are much lower.

PTM7950 and Upsiren UTP-8 are magic at this point. No idea why it's not industry standard.

I got both off of Aliexpress and they arrived pretty quickly.

I just got some Upsiren U6-Pro thermal putty off aliexpress to throw into an RTX 3080 that I got for next to nothing, so I'm keen to give it a crack. I've still got some Arctic MX-4 thermal paste, so that'll be going on the core, however I'm also keen to try a sheet of PTM7950 for this at some stage.

It's hilarious that the knockoff stuff seems to perform better than the original according to random internet people.

It's way cheaper than thermal pads, and it can be reused multiple times if it's still making good contact between the components and heatsink.

On a side note, this is why you don't trust AI!

Definitely give PTM7950 (And similar phase-change pads) a shot. They last for ages and never pump out pretty much, and the results have been pretty impressive.

Don't use MX4 on a GPU, it has really bad pump out issues (The liquid escapes with heat cycles and GPUs are the worst for causing this)

PTM is the best because it avoid this, but MX4/5 is one of the worst for direct die stuff it can leave dry spots in months on a GPU.

Which can lead to crashing as GPUs cant handle dry spots like a CPU IHS can.

Thick pastes are generally better for direct die stuff (Again due to lower liquid content, usually means longer lasting) though you need to warm them up to get them more malleable or just use a spatula and really spread them.

But it would be best to spring for something performant and well rated like Thermal Grisly, that both will cool well AND do it for quite a long time.

You did a good job with the putty/paste.

Tots of people just put a ball in the middle of the chips / die, not realising how much more important full cover is on these is for a laptop, compared to a desktop CPU IHS.

Yes it can be a bit annoying when people say "just use paste bro" when they haven't got any experience, but as Lauryn Hill said "Forgive them, Father, for they know not what they do" lol.

Following quite a bit of research over the last few days, I was really keen to try and get some Upsiren putty for the VRMs, and even some PTM7950 for the CPU and GPU, bit couldn't find any for sale locally.

Your numbers look amazing btw.

Thanks! I watched a ton of tutorials and did my best with the VRM paste, but warming the paste would've been a good tip to know before hand as the cheap HY234 was pretty hard to work with.

The results on the G15 were so significant, that I was asked to do the same on a Strix G14:

This was a bit harder to do, and I'm not sure if the smaller 14" Asus laptop runs inherently hotter, but after repasting, ingame temps for fortnite were at 80C, which is still ok, but not as cool as the G15 at 70C. I think PTM7950 would be really interesting in the smaller, hotter laptop.

It's magical honestly. And I legitimately did not know my gpu hotspot was 105 degrees celsius. Lowering that down by 30 - 40 degrees is insanity, even at full utilization.

And yeah I had to do alot of research into ptm and upsiren putty, but it was well worth it. Honestly was worried I didn't put enough putty as one guy who's done it says I likely should've gotten double the amount.

Above pictures gone, here's an after and before album on imgur.

I just double checked, and it's MX-6 which is thicker than MX-4. Anyway, I haven't yet applied it to the GPU, so I might just hold off and get some PTM instead to try it out.
