GL504GW K5-Pro Thermal Paste

[TX2000]

I went ahead and bought K5-Pro for my laptop.
it comes with a stick to apply so i went and took a syringe and filled it up . (is a lot easier that way)







so far so good still testing

good temps so far

I think K5 Pro is still the best option with these ASUS thin laptops... Pads (even the good ones, and with every thickness between 0.5-1.5mm) can cause troubles because surfaces (both VRM chips + heatpipe) are not perfectly smooth and irregular. Many users complained of strange issues after using pads: stuttering even with good temps, strange variable temps for CPU/GPU… Only a very few had success (or maybe they just stopped writing in forums too early to report minor issues later). All in all using a thermal paste like K5 Pro grants best heat spreading, despite not exceptional W/mK (which seems less important though).

Yes i had i had pads that were higher on temp transfer but the heatsink is so uneven and you end up putting double on some parts and causing trouble on others.

it was working fine but now it runs alot cooler and i got higher FPS. Maybe the vrms werent transfer heat that much idk.
Also i used cool laboratories liquid metal. I just reapplied again because i removed the heatsink. And it it was still in place.

The problem with high performance pads are not the thickness, but well, their performance compared to what comes stock from the factory, k5-pro.

By using high performance thermal pads you're dumping even more heat into an already saturated heatsink. VRMs don't need to be cooled as much as CPUs and GPUs do. They are usually rated to 120c or more and are probably working at around 90c from the factory, which is totally fine. You will gain literally nothing by lowering those temps.

Are you sure of this theory? It makes sense but… Did you test yourself different pads with different W/mK?

[FULLMETALJACKET7]

Yes, tested it myself on an old Lenovo y510p (gt750m SLI + i7 4700mq). I was fighting a really good fight regarding temperatures with that laptop. It probably has the smallest heatsink I've ever seen on a gpu, no joke.

Another big problem is that in some models the heatsink mounts are not designed to have a "crushing" force strong enough to squeeze the pads properly so the heatsink makes good contact with the dies. They're not designed for that. Using very thin pads is just a work around for a problem that didn't even existed in the first place. Back in the day, people used to install stronger springs in the case of the y510p. That only caused yet another problem (that also didn't existed beforehand) which was pcb warping. Few months later, bga issues. Mine is still working to this day on the stock springs, k5pro and Arctic mx4.

My 502vs is still running fine on the stock paste but I'll repaste it using k5-pro and good quality paste on the dies, when the time comes.

After many tests using Arctic (6W/m²K), Gelid Solutions GP-Extreme (12W/m²K) pads 1mm, 0.5mm, or K5-Pro, and using thermal paste Noctua NT-H2 and Gelid Extreme I can say best results are with 0.5mm pads Gelid Solutions GP-Extreme + Gelid Extreme. K5-Pro wasn't any better: maybe it's good because it's sticky so it's safer for best contact, but in the end the theory of slowing down VRM's heat dissipation using K5-Pro (~5.5W/m²K) wasn't correct. Best solution was using the highest W/m²K THIN pads.

Gelid Extreme was also the best paste: reduces A LOT thermal throttling chances. In other words where the other pastes reached for a few sec 91-93, GC Extreme did a better job keeping in many situations temps around 89-87 even at spikes. Sometimes Gelid paste also reached 91°C but never caused thermal throttling where the others above 90°C always triggered throttling (using HWiNFO). There will always be spikes up to 93-95°C possible using synthetic stress tests like AIDA64 but this seem unavoidable (i7-8750H). Best curve was always with Gelid Extreme thermal paste.

I have a gl703gs, it has thermalthrottling and I repaste with thermal past Kryonaut and thermalpads 0.5 mm gelid extreme, for 40 minutes it was awesome 70°-75° in game both gpu-cpu, then the cpu temps grew gradually till 97°!!, I read this post and its very possible the relation of temps and termal pads, its transfer a lot of heat of vrms to the pipes.
but I don understand why the gpu max temp it's only 74° (it a good temp)

Now Im wating a k5 pro and make test

hey guys, thx 4 the information
i'm from brazil, and u guys know here's like hell, so hot, those laptops are not designed for this climate...
i've been strugglin with high temps (95-97ºC on cpu) and thermal throttling since ive bought my gl502vmk...
ive tried those grizzly, AS5 and mx4... and i always noticed when repasting that my gpu/cpu die wanst sufficient. i also undervolt my cpu and use cooling fan base...
read this topic today and already bought my k5-pro and maybe u guys solved my laptop thermal problem...
when i get everything done, cleanin on fans, repasting cpu/gpu die with mx4 and gpu vram with k5pro, i'll come back here and tell how it was

It seems every pipe is slightly different (even half millimeter can make a difference! And the 8 screws system by ASUS is not reliable...). This explains why some have solved with thick pads (big gaps). Others with thin pads (small gaps)... some others with K5 Pro only (very small gaps)... You can also try with paste everywhere (use a cheaper one for the surrounding chips), not only on the dies as it's been reported to work fine as well by some users!
K5 Pro dries quickly in 3-5 months and leaves small holes like Swiss cheese! I do not recommend it as I've used it.

Best choice from my experience is 0.5mm pads for VRAM etc (4-6W/mK max, you don't need higher as it can be worse) + 1mm in some cases on silver squared VRM Inductors and MOSFETS, over the CPU area... and thin dot(s) of Gelid GC Extreme on CPU/GPU.
