Deepcool G40 works great on my Dell Inspiron 15 7506, it is one of the best I have ever tried. I finished my new test and also included 5 reference pastes including Deepcool G40. MX-6 is a big improvement over MX-4/MX-5, although it's not reaching the very best but it's a solid paste and cheap. I'm sure it will be more competitive on most other devices. Corsair XTM70 is better but cannot reach my best pastes. Arctic MX-6 21.5 73/79/75/75 Corsair XTM70 21.2 73/77/74/75 Deepcool G40 21.3 71/75/72/73 Thermalright TF9 21.3 72/76/73/74 Alphacool Apex 21.4 73/77/74/75 Arctic MX-4 21.5 79/82/81/80 Akasa T5 ProGrade Plus 21.5 73/76/74/74

Why is it an excuse, did you even understand what they said? Basically you are saying they could give you a fake W/mK and then you are happy, that's all you need. They can easily specifiy a high thermal conductivity, this is not the problem. You are also claiming a proven paste like Noctua NT-H2 and some other famous pastes suffer from underlying performance issues just because they don't specify a thermal conductivity, it's nonsense. Honeywell PTM7950 paste is specified only with 8.5 W/mK, it should be much worse than all the 13, 16, 17 W/mK pastes right? Sorry it's not that easy.

I cannot test Kooling Monster KOLD-01 because they scammed me, there was no paste inside the package. This is really disappointing because I was curious about this paste I'm currently testing Arctic MX-6 and Corsair XTM70.

This is the reason: FAQ: Why doesn’t Noctua specify thermal conductivity or thermal resistance of NT-H1 and NT-H2? https://noctua.at/en/why-doesnt-noctua-specify-thermal-conductivity-or-thermal-resistance-of-nt-h1-and-nt-h2

W/m*K is mainly a marketing number, it really doesn't tell much and nobody knows if it's real or just a fake number. That's why some manufacturer won't even share it. Is there a W/m*K number for Corsair XTM70? I haven't found. Some of my best pastes have a low W/m*K number, for example Deepcool G40 or Akasa T5 ProGrade Plus and some with a high W/m*K are poor performer.

Is it the 2022 version? The pre 2022 SYY-157 was even thicker and better performing on my notebook. Arctic MX-6 is out. According to first tests it is higher viscosity than the MX-4 which is good news. There is a good chance it will perform better on a notebook, hopefully much better in my case considering the MX-4 was several degrees down. I have ordered MX-6 as well as Corsair XTM70 and Kooling Monster KOLD-01. I'm curious how they will perform.

Nanogrease is complete crap for my notebook.

Here is another test from the Corsair XTM70: https://www.profesionalreview.com/2022/10/14/corsair-xtm70-review/ However the peak and idle differences doesn't make sense. In idle 3-7 degrees difference can't be accurate, maybe the ambient temperatur is different. Interesting paste though, hopefully I can try it out sometime. 25-30€ for 3g paste isn't cheap by the way.

@jaybee83 https://www.arctic.de/en/blog/arctic-press-information-on-mx-5-thermal-compound There were many customer complaints on Amazon and some time later MX-5 completely dissappeared. This paste was a big failure. There are videos from a bad batch, here two of them:

Arctic MX-6 is coming late October, listed on Amazon: https://www.amazon.de/ACTCP00080A-ARCTIC-MX-6-4g/dp/B09VDL3CW6?ref_=ast_sto_dp I hope it's (much) better for notebooks than MX-4 and MX-5.

2022 edition isn't neccessarily worse for you, my cpu/cooling is very sensitive to the viscosity. In other tests it could perform better.

I tested some new pastes including the 2022 edition of SYY-157. It is noticeably less viscous than the 2021 edition and it seems it's not as good for me. Also retested Alphacool Apex and it confirmed my first testing, it's a reasonable paste but it's not matching the best. This paste and the new Thermalright TF9 is quite a bit more viscous than SYY-157 2022 edition. Alpenföhn Permafrost 2 is the most watery paste in this test - great performance considering it's not that viscous. Apex almost 1 degree behind with a much more viscous consistency. In my big test early this year the Apex would have been placed between 15-19 I think. SYY-157 2021 edition 25.6 74/81/79/78 SYY-157 2022 edition 25.7 76/83/80/81 BSFF BS-139 25.2 78/82/80/80 JLJ TP-133 25.3 78/83/80/81 Thermalright TF9 25.3 75/82/79/80 Alphacool Apex 25.6 80/83/82/82 Alpenföhn Permafrost 2 25.7 79/83/81/81

HALNZIYE released a new paste called HY-P16 rated 16.1W/m-K (doesn't tell much), the interesting part is this: https://www.halnziye.net/product/237.html I have to try out this paste as well as Honeywell PTM7950 at some point.

I have tried out two new pastes on my notebook, for reference I included SYY-157 (2021 edition) Alphacool Apex 82/87/84/84 Scythe Thermal Elixer 2 83/91/87/87 SYY-157 2021 edition 81/83/83/82 Thermal Elixer 2 is medium viscous and not working. Alphacool Apex is a viscous paste, viscosity is comparable to several other Nano pastes I've tried. Much better than the old Alphacool Subzero which wasn't viscous enough. Maybe I could improve the Apex result with a second application slightly, even though the gap is big enough it certainly won't match the SYY-157. I'm fine with the SYY-157 for now and won't give Apex a second try.

This thermal paste test is interesting (chinese only unfortunately) https://youtu.be/2Uc1lrfFnsc It's a longevity test. Here is a transcript from the test: https://forums.hardwarezone.com.sg/threads/thermal-paste-specification-comparison.6677965/page-9#post-142742642 This is what they did: Sure we could argue how realistic it is with a temp of 200 degrees but still, it could explain some longevity issues from some pastes. For example TFX has very good initial temps in basically every test (including my tests) but there are quite a few degradation reports. In this baking test TFX failed, several other pastes failed as well. What is the reason? One post in the hardwarezone.com.sg forum explained it. The Kingpin Cooling KPx has the lowest degradation after baking which surprised me. However the best baking performance comes from a paste called GK5. The best pre baking performance comes from Thermalright TFX and W15II but both failed the baking test.

Is there any comparison between the pad and paste of Honeywell 7950?

When it comes to the package it looks legit to me. Same from a reliable shop: https://www.mindfactory.de/product_info.php/Arctic-MX-4-2019-Waermeleitpaste-4g_1290084.html Or Arctic:

The package/tube looks legit to me, it's the same in several chinese tests from Honeywell pastes. Honeywell 7900SP offers the same performance as 7950 in this chinese test by the way. 7950 has a longer curing time but maybe it means the longevity performance is better on the 7950. https://bit.ly/3KoSt7X

There are indeed several of really encouraging tests for the Honeywell PTM7950, interesting paste. There is also a newer PTM7958 used by Lenovo: https://www.reddit.com/r/LenovoLegion/comments/tfxomi/lenovos_stock_paste_is_actually_ptm7958_a_custom/ I looked into this spec sheet: https://thermalmanagement.honeywell.com/content/dam/thermalmanagement/en/documents/document-lists/marketing/ThermalInterfaceMaterials-Electronics-Brochure.pdf PTM7000 series has a thickness range of 0.2-1.00mm which is really good for bare die CPUs and should work on my uneven i7-1165G7. There is also a TG series of thermal paste, TG5500 has a viscosity rating of 300,000 cps. Lower thermal impedance rating than the PTM series but also a lower thermal conductivity. Maybe the thickness range is lower.

Yes it's me. Strange, I thought I registered with Rooter1234 lol. No problem anyways.

You can buy it from Amazon (One enjoy store), it's available there.

The manufacturer of SYY-157 Nuomi Chemical (Shenzhen) Co., Ltd. released two new pastes: - BSFF BS-139 - JLJ TP-133 BSFF paste is available on amazon.co.uk. The thermal conductivity rating is lower but this isn't necessarily a meaningful metric. Viscosity on all three are 200.000cps.

As some probably know I did a new big test early January for most of my thermal pastes on my Dell 7506. You can see my collection (60+ thermal pastes) in the photo from below. This is a copy and paste from my test which I originally posted on notebookreview forum. This is the average degrees of 4 cores+ambient temperature correction (between 0.0-1.0 degrees).

We know that TFX has superb temps initially but we also do know that there are quite a few reports about degrading performance in laptops. I hope Cryofuze does better in the longer run. Another paste I liked was the Alpenföhn Permafrost 2, it is really nice to spread. It's not thick but still great performance, the first 6 are a lot thicker. Could be also a good choice for desktop CPUs.
