Seems like you can get PTM7950 from Amazon but its under a different brand but it seems to be legit according to the reviews

unless someone here can test and compare to Honeywell one.

Yeah, according to the reviews and others asking questions about the pads it seems to be legit

[ryan]

I saw from a few youtube videos the honeywell thermal pads actually work extremely well and can lower temperatures under load by 15c and at the very least if your laptops set to auto fans lower the fan speed. I think im going to order 2 applications and get it done in a shop as I think my motherboard is upside down and would be a pain.

[KING19]

I might have to be a guinea pig soon because i just ran out of the paste version of Honeywell 7950 after repasting my laptop and my GF's laptop. Seems like the average lifespan of the paste is 6 months before the temps start rising again. Amazon has a good return system if these pads are garbage then again I could always buy the real honeywell on ebay if i want it quicker than buying from ebuy

[ryan]

Im done

 

I bought honeywell phase change pads and the performance is awful, just as bad as that noctua stuff I bought years ago.

 

here is a proper review from 2011..  diamonds are still the best based of reviews

That's odd. Did you wait for like a day under load for it to set/cure properly?

[ryan]

3 days. its terrible, perfect application. I put it on when I installed my SSD and Ram. literally worse than stock. now im in the upper 90s underclocked vs upper 90s overclocked, there must be a 10c difference or worse. I am never trusting again. Ill just test things out on my own

[Etern4l]

That’s contrary to everyone else’s experience. Either you got sold a fake pad, or something is terribly wrong with the laptop/heatsink. 😞

Mine was terrible as well. Probably aliexpress fake

i guess I got lucky with my batches from the ebuy7 and eBay. In my limited experience though, the factor that best explains poor temps is bad heatsink fit/geometry/pressure. Heatsink not being an issue, good pastes perform similarly, although durability may vary.

very helpful, thanks for the input guys!

 

since ive been out of the loop for like 9 months, whats the conclusions so far with regards to the honeywell pads? where does it slot in vs. high end pastes like kryonaut extreme / KPX / liquid metal?

Real PTM7950 performs like a perfectly spread high-end paste like TFX. People claiming no difference between PTM and LM usually have a vapour chamber heatsink (like lenovo users) which helps deal with the higher thermal density.

 

Otherwise there is still a 5-10C difference going from PTM to LM.

 

For desktops it's a whole different story though, the soldered heatspreader already helps reduce the thermal density and coupled with beefy cpu coolers so the differences in pastes are much less obvious than in laptops. (which for all intents and purposes are basically "direct die")

 

That said, I believe you all know the clock is ticking. You already get more benefit from direct die cooling on desktop than ever before so even the soldered heatspreaders are becoming a bottleneck.

 

They could always move to a vapour chamber heatspreader though.

 

I'm starting to wonder if my 7945hx is thermal density limited even with LM + vapour chamber. Running prime95 + furmark hits 90C peak on the cpu and 72C on the gpu with 400w combined heat load. But just prime95 still sees the cpu peak at 85C even though its just a 180w heat load. 

[Etern4l]

Mine were all grey, including the 7958 paste, I think.

 

 I’m tempted to move up to LM. Temps with 7958 are OK, but would expect more of an improvement on a delidded CPU.

[Eban]

I thought mine was grey also...but it has been a while.

Good tip to know!

if the 7945HX behaves the same with regards to thermal max boosting and the stock thermal limit is the same at 95C then your chip should be maxxed out at 85-90C. but naturally, any additional thermal headroom could come in handy for additional oc 🙂

Thermals isn't the constraint, the 108A TDC limit is.

 

Just waiting for UXTU to support dragon range.

ah yes u mentioned that before. in that case u could go the UV route to save on amperage and potentially free up more headroom (unless uve already done so).

Have you tried uninstalled Asus's thermal or power driver framework? I had 5875U Thinkpad that had worse thermals after swapping the paste with ICD Pad, in my investigation OEM allowed much higher voltage and TDP to push CPU and you will not see current limits or thermal limits until 100C. Blacklisted the said drivers in Group Policy and thermals dropped by 40C from 90-95C to 40C. Maxes around 65C in passive mode.

Also Skip UXTU that makes performance worse than stock windows. Just use Windows 10/11 Power Slider. Optionally replace Asus's Radeon Driver for Nimez Driver if AMD iGPU is present as you can adjust if you prefer Performance from Discrete or use as APU to optimize power and performance.

Vasudev my man, havent seen you in forever! how are things? 🙂

Should I get liquid metal by thermal grizzley? or do you guys still swear by honeywell phase change pads? i'll give it another go but im not liking the odds. with my stock paste I would throttle but my cpu score was up to 11000 in timespy. and with the honeywell pads I am around 9800 max. I need to repaste with something as my games are either stuttering from 8gb/32gb ram or thermals. im using the phase change right now and this thing is getting hot. maybe we could do a before and after (PCP vs liquid metal) but if im getting higher temps than stock tim whats the point

 

as for ICD I have never ever after owning 10 or so laptops applied it and had  worse temps than stock, its always a 5c-10c improvement, in a worse case I would see temps stablize around 90c but usually with each gen of cpu the temps would stop rising around 80-87c. right now i have to lock vsync on to prevent overheating.

 

ok found it

Thermals aren't the constraint, neither is tdp. TDC is.

is it worth buying again or switching to liquid metal...it would just be nice to run stock clocks for an hour without 96c

I swear by LM on the cpu. Gpu you'll get by using any high end paste.
