thermal paste Which Thermal Paste to buy and apply (Traditional and Liquid Metal)

[Rofa1234]

I did a second test with Heatphase Ultra with identical temperatures to PTM7950. Consistency also identical to me, specs identical as well by the looks of it. It is very likely this is a simple rebrand of PTM7950.

so in the end only pricing matters

Too bad, I thought this was a reusable solution 😞

 

I guess in the grand scheme of things it is good that people now get this product from Gelid instead of something inferior but to those of us "in the know" this is not helpful at all.

I think it is within margin of error. Need to be tested on laptop heatsink with lower pressure to see if it performs better than carbonaut or IC HC pad. In my case with carbonaut and HC pad both 1-2C worse than cooler master maker gel nano paste but its been 3 yrs on carbonaut and 1.5 yrs on HC pad thermal performance has not worsened even at 40-45C ambient temp.

One question, you mean the cooler master maker thermal paste was better but lasted less time?

Correct. The paste lasted only 5 yrs until I noticed consistent spikes to 90C and throttling. Carbonaut has steady temps for 3yrs and maxes out at 70-80C.

Here is a test with 25 pastes/pads on a GPU:

huh? kryosheet beating kryonaut? O.o

[Rofa1234]

Kryonaut didn't work on my laptop because of a bad contact. On a laptop it is a risk trying it out. If it works it can be great.

yeah laptops are better off with a more viscous paste due to higher variability in heatsink contact. kryonaut is rather thin and suffers from pumpout over longer periods of time. but freshly applied its pretty solid.

i wonder if kryonaut extreme / KPx is better in that regard? still have a huge tube of kryonaut OG, so not planning to get a new paste anytime soon 😄 

[Rofa1234]

I made a mistake, I meant to say Kryosheet didn't work, it hit 100C very fast. On uneven low pressure laptop heatsinks it is more limited than PTM7950 or a medium-high viscous paste.

[Vasudev]

I just spring cleaned the alienware 15 r2 after 4 years with Carbonaut. Got it in 2020 before Covid19 and replaced few worn out thermal pads. It was hitting 90-95C for no reason due to clogged fans.

@Rofa1234 By any chance is the ICD graphite pad the older one released before Carbonaut? I got newer HC pad that is similar to TG Carbonaut at lower price almost half with 5 packs. Its just 1-2c worse at max temps than TGC.

Recently repasted i7 9850H (Dell precision 5540) with some not-big-brand stuff.
100% cpu spikes to 100c then quite quickly settles in lower 80's, sustaining good turbo values. Near-idle ok.
Results decent? Any reason to try another paste?
Thanks

that is high.  . why not try Honeywell ptm7950 paste.

Thanks for the hint that it should\could be improved. Will do some new pasting test in the future. Am suspecting this Precision of not having any audience-awing cooling\fan capacity by design.

Anyway, not often I need to stress it (does the job, apart from heat+fan noise), but highly appreciating the total silence \ lowish temp under normal\medium daily use.

could be a bad repaste job.? paste not spread evenly. or uneven force of screws spring. i like mine running the coldest posssible.

 Can you provide of close up shot of CPU and GPU(if it has one) die shorts and heatsink? We can figure it out. 90% chance are uneven pressure due to Dell horrible QC. Due to similar issues I simply switched from thermal paste to carbonaut and ICD sheets.

Replies appreciated. Will investigate..

Here you go. Fans\vents clear. At first sight, can't spot any obvious catastrophy, either pasting or contact surface.
Pushing on top of cooling conduits, the contact surface to processors seems to be mating very well, flatly. Maybe too much paste? Appreciating any input.

The paste, enthusiastically named "Plexgear MX990 Carbon Freeze", claiming 11 W/mK2

Nvidia left, i7 right. The heat figures posted earlier, only i7 in use.
 

Edit, pic of cooling system (looks well designed, but...?)

hello ladies and gents, just wondering if you could help me find a legitimate seller of the phase change pads, Im looking for the official version to try out as my laptop is getting toasty even with the iets gt500 99c with 4.2ghz basically stock and a decent load, and even after undervolting. im really excited about the pads but i dont trust ebuy

[raptorddd]

are there heatsink with 3 pipes.? ive only seen 1 and 2 pipes.? if you place a pipe on top does that helps to cool.?

have always asked my self. one end of pipe enters heat then travels from cpu side to end side to fins.. but if you add another pipe on top does that helps to cool down.? longer to heat .? more heat.?

Heatsink pressure on CPU is very good but on GPU top right is slightly warped which might cause issues with LM or carbonaut/kryonaut/icd sheets. Is the VRAM chips cooled with thermal pads in the back? Atleast you can service it easily whereas my Dell mobo is inverted.

Maybe I'm wrong, is the 2 & 3 numbered screwed in very tight?

You can add 0.5/1mm soft thermal pads on VRM just above the number 3's which should reduce temps by 1-2C.

Thanks for replies. Looks like there is nothing basically wrong, except that the thing runs quite hot by design when stressed. No real problem in practice here. Surfaces looks flat \ good contact, screws \ springs all ok.

Did a few more repasting tests, with more or less paste, differences were of no practical importance > cool enough (silent) with low utilization, more heavy demands the usual jumps to 100 with fans then bringing it down in the 80s.

Am leaving things as they are ftm, will someday try another brand \ type of paste. Yes, a good thing, access very easy. A picture of the complete cooling setup.

will find out in a few hours if PTM7950 lives up to the hype. hopefully I can get my temps under 100c with an overclock. took pictures of before(stock/OC) and will be able to give a definitive answer

u going with the paste of thermal pad? wasnt it that the paster performs worse than the pad? might be mistaken tho! in any case, keep us updated on your findings 🙂 

[ryan]

yep it helps/

 

dusting and paste had to be done and its the ptm pads

 

temps before upwards of 99c now around 70c on gpu and 85on cpu with 4.6ghz so lower temps with higher clocks.

 

with the settings ill be using for gaming undervolted and overclocked gpu and cpu set to 4ghz(200 under stock) I get 56-65c stabilizes at 61c ill run a quick run

 

62c on gpu and max 66c on cpu average 64c

 

pretty dramatic decrease. well worth the 30 bucks...only a 15-20c drop in temps(dedusting also) no biggie lol but thats with a de dusting I think before i was getting similar performance, the pads work well dropping temps by 5-10c.

 

 

also now I can overclock and game for hours and hours, god of war runs at 32fps average ultra dlss off
