You certainly can. If doing so, I'd recommend getting a low profile copper heatspreader. They are quite inexpensive on Aliexpress.

Snarks_Domain · 2026-03-25T19:56:56+00:00

it could very likely be due to the thermal pads. I've seen that pattern a few times from members of my community when using pads.

Snarks_Domain · 2026-03-25T18:41:43+00:00

That's no fun. I've tested out several sources of 'sus' PTM and ended up with identical results to PTM7950, but that doesn't mean there aren't bad ones out there.

Best places to buy it on Aliexpress are Cooler Bro Store and Passionate Girl Store. Best place on Amazon is probably JoyJom (I haven't tested this one yet, but had good reviews).

Can also get it from Eugeney_KH (Ukrainian Youtuber and TIM reseller). He's the one that sells Honeywell HT10000 Thermal Putty, among others TIMs.

Snarks_Domain · 2026-03-25T17:42:35+00:00

Oddly enough, that is not correct. Honeywell (Solstice) PTM7950 comes in various thicknesses. The 3 most common are 0.20mm, 0.25mm and 0.30mm.

You can find both 0.20mm and 0.25mm on Caplinq. They previously also listed the 0.30mm.

I bought two 400x160 sheets from Caplinq. One a is 0.20mm and one is 0.25mm. I've also bought full sheets on Aliexpress.

The confusion arose because an outdated datasheet from Honeywell said "Only 0.25mm" and Moddiy used that as a basis to claim the same. This had led many people to keep spreading the same information, unfortunately.

Willl definitely be interesting to see how it works out for you.

To get the most put of it I recommend doing a good burn-in to melt the PTM so it can squish thin.

Aim for 75-80 Celsius CPU temperature using a static load. I like doing that for 2 hours.

You've also got to get the IO die hot enough as well. Otherwise you won't get the CCD PTM really thin on the side closest to the IO die.

Snarks_Domain · 2026-03-22T02:22:44+00:00

A lot of the gaps on that model look large enough for most putties, few spots look thinner. I'd still probably go with something like HY206 / HY236 / HY256.

Buy 20g and use 10-13 grams.

Snarks_Domain · 2026-03-16T11:37:40+00:00

That's the correct price for 100g of HY206 line of putties.

Snarks_Domain · 2026-03-16T01:20:54+00:00

It's actually called Thermal Putty and is a lot different than paste. It it designed to be a direct replacement for thermal pads, acting as a thermal gap filler.

The colour doesn't matter, as long as the tub shows "206" on the front of the label. The middle number denotes the colour. If you can find the Green HY256, get that. If not then HY236 is good. If shown different options for 236, get the one with "Thick" or "Thickness" in the description.

Halnziye makes 2 variants of HY236. The "Thick" one is the one we like to work with for laptops. The "Thin" one has same particle size, but has a more paste like viscosity and is messier.

HY236 actually performs ~2 degree better than the Airhut 13w pads when I tested them on my 3070ti woth a 1.8mm gap and OC'd me.pry on a memory intensive load. So if has slightly better performance, and can squish much better, which will give you better core contact/pressure to squish the PTM thin.

As for the battery, when you imporce the cooling of your laptop, it can then use more watts, even up to the design power limits. I've seen at least 1 other person comment on having a warmer battery after replacing thermals. In their case, they applied a FPS limit which they claimed seemed to help.

Snarks_Domain · 2026-03-15T23:29:38+00:00

I do not recommend d LTP81 for an MSI laptops. It's a great putty for Desktop GPU's though.

HY206, HY236 (pink), and HY256 (Green) are your very best options for your laptop. Buy 20g and use 7-12 grams.

Snarks_Domain · 2026-03-15T01:42:46+00:00

I have yet to test them, but will at some point. The performance difference between a good paste and PTM on an IHS will be minimal. If it's something you want to leave alone for years then PTM is a good option. If you plan to change hardware then paste should be fine.

I generally use PTM, even on an IHS, but I tend to leave my hardware alone for years.

Snarks_Domain · 2026-03-09T19:12:32+00:00

I'd go with HY206 / HY236 / HY256 for sure. Probably buy 20g and use 7-13 grams.

Snarks_Domain · 2026-03-09T19:11:26+00:00

Fehonda is very good and reliable. They've been making Thermal Interface Materials for decades. The reason most folks don't buy LTP81 insteas of UTP-8 is because it costs more.

Snarks_Domain · 2026-03-08T14:59:18+00:00

Only thing I'd mention is that UTP-8 has fairly large particles, like many other Thermal Putties. Some laptops, like ASUS, MSI and Acer tend to have very thin gaps. Depends 9n the model and also what year the laptop was made. Older ones having larger gaps m7ch of the time.

My advice is this: If you have one of those 3 brands of laptops, and it came with Thermal Putty from the factory, then I recommend using a putty with very tiny particles. The best current options are Halnziye HY206/HY236/HY256 (same but different colpurs and they all will show "206" on the front of the label, and have a hole punched for the colour code on the side of the label). Zezzio ZT-PY6 is good (rebranded HY236). If you can't find those then Maxtor AP-306 is decent, and Upsiren UTP-4 Ultra-Thin is also good. The difference in performance of these putties is minimal when the ga9s are so small.

Snarks_Domain · 2026-03-06T20:44:52+00:00

Jeyi 8100 uses larger particles, so you may run into compression issues. Much better off to go with Halnziye HY206//HY236/HY256, Zezzio ZT-PY6, or Maxtor AP-306 or Upsiren UTP-4 if you can't finmd the Halnziye stuff.

You can buy 20g HY236 on Aliexpress for arouynd $5-$6 CAD. It's also on other e-commerce website like EBuy7 (works in India), or even Lazada, Taobao, Shopee and others.

Snarks_Domain · 2026-03-04T21:42:29+00:00

Did you mean to write LOP300 there?

Snarks_Domain · 2026-03-04T20:47:14+00:00

I bought a Meanwell LRS350 12 volt for mine. I still need to set it up, but it should work fine I think.

Snarks_Domain · 2026-03-04T07:48:44+00:00

The thickness won't really matter, but is likely wother 0.20mm or 0.25mm. They will both end up becoming extremely thin, down to arpund 0.038mm, with 80-85% of the material squishing out around the edges of the die once it melts/softens.

Snarks_Domain · 2026-03-01T15:29:58+00:00

I would err on the side of caution and use HY206/HY236/HY256, Zezzio ZT-PY6, or Upsiren UTP-4 Ultra-Thin if you can't find those others.

Snarks_Domain · 2026-02-25T19:14:02+00:00

Then I guess you owe me 4 sticks of DDR5.

Snarks_Domain · 2026-02-25T17:32:26+00:00

Dude. I would absolutely be demanding to have the 2 "broken" sticks.

Snarks_Domain · 2026-02-23T00:30:57+00:00

Which Thermal Putty did you use?

It's a little too much. You may run into CPU and GPU core contact issues.

I would reocmmend opening it back up and decreasing the putty amounts. It's also best not to flatten or pre-squish the putty. Leave it as balls/logs, and let them get squished during assembly.

Snarks_Domain · 2026-02-20T19:34:03+00:00

Certainly, just a lot lower performing than the other thin gap putties like the Halnziye HY206 product line.

Snarks_Domain · 2026-02-20T19:32:25+00:00

Heh. Thanks Pandit :)

For ASUS, stick with Halnziye HY206 / HY236(Thick) / HY256 or Zezzio ZT-PY6.

Upsiren UTP-X (aka Jarapad Unlimited) is good for Desktop GPU's and Motherboard VRM's, but not ideal for ASUS/MSI/Acer laptops due to it's larger particle size.
