Its not terrible, its great for low to mid loads on my 5600X, but at high loads it starts to lose its grip in the low 60s on my other heatsink. I haven't used AS5 on this heatsink yet. :D Its easier to see it on an Intel because you can see individual core temps.. pretty helpful.. On my x5690 I try to maintain a 3-6c spread. On my 3770K I am ok with 12c because one core just does its own thing and gives no effs.

Though maybe I should do my own comparo between TF7, AS5 and SYY-157 with very few notes and maybe a few screen caps to show I'm not full of it :laugh:

Sitting here doing nothing she will sip on 65w @ the wall.. but load her up full of linpack extreme and she starts pounding back 370w like a big girl. Its actually pretty impressive. My x5690 is fairly similar, except with a decent oc and C1E and SS off she will idle at about 265w.. shes gross. I keep her locked away for good reason.
 
Sure, hopefully they lie when they say the end of the month.. but it took 3-4 weeks to get my Thermalright bolt through kit from Nan's. Normally it only take a week or less when I order from there.
 
Hi,
Not sure why noctua added so many alcohol wipes with nt-h2 but it pushed the price way up
The wipes weren't very good either way to wet and took for ever to dry pretty much like the paste too way to wet.
Put some tg hydronaut on my 10900k last Friday evening and reapplied 9940x with mx-5.
Too busy to do much atm.
 
what about thermal grizzly conductonaut? I got 20 celsius drop in temps from that on my laptop... desktops don't see that kind of gain but i think they still can get a 5-10 celsius drop from conductnaut depending on the cooler used.
I used Conductonaut on the 6900XTU Liquid Devil Ultimate. It is good when you apply it directly on Die like Delid CPU and GPU.
The results are amazing with 15°C drop in hot spot temperature from 92°C in stress test to around 77°C .
I bought also MX-5 but used it to isolate exposed componenets around the GPU Die before applying LM. :laugh:
It is nonconductive and really stick and I find it better than nail polish to isolate exposed componenets around 6900XT Die. :D

On the 5900X, I am using Thermal Grizzly Kryonaut.

@Felix123BU tried Liquid Metal on 5800X CPU and there it only gave him very few degrees better but directly on Die it makes a big difference.

That's actually a really creative use for it! I'm guessing it worked perfectly too.
 
Hi,
Yep thermal paste is a lot easier to explain on rma issues lol

Bottom line looks like nt-h1 is still best out of the pastes I have used pretty much why I keep using it but contact and core temp spread tells the story on how good contact is as usual

Funny one I updated to 21h2 and r23 was no where in sight pinned to desktop downloaded to videos folder so I had to download r23 again lol

Other screen shots here

TG hydronaut
Score is a little higher but so is max core temp by 2c from mx-5's 84c
Spread is at 10c 76-86c so that too is a bit more than mx-5's 75-84c

9940x at 4.9 a bit different than 10900k results thought mx-5 would do better
Used hydronaut on this r23 sub last year looks better

Now with mx-5 at same 4.9

Nice. 2C difference. Almost margin of error.

To be fair though TG Hydronaut is about 5x more expensive at 1.5grams for nearly $13.
Compared to MX-5 at 8grams at $12

This comparison once again firmly puts MX-5 in the same class as the premium priced TIMs.

Hi,
I sure didn't pay that much but likely 24.us for 5 grams so at least 50% more.
 
We can start comparing to the price of Gold which is about $60 a gram; $10 a gram seems rather high for a thermal paste.

GD900 is about 15 cents a gram

Sorry to bump this thread, but I just noticed the 54k in views, holy crap everyone. I am so sorry. lmao if I had known there would be more than like 4 people and a few replies interested in this, I would have went out of my way (back when my mx-5 first arrived) to get temps posted. Really apologies everyone.

in other news, I got some NT-H2 and updated my laptop cooling, which you can see over here if your interested:

 
I will not use conductonaut or lm based paste due to reaction with aluminum, (corrosion)
 
@Andy Shiekh any idea if white lithium grease would be of any use in cooling or in say fan longevity on the spinning parts? or lets say... coil whine? I honestly can't find much on it.

I was told by my Dad that this is better than WD-40 for squeaky door hinges and stuff. When I actually read what it is though, it got me curious... LOL but I don't want to risk it on my gear.

@lexluthermiester its considered extreme friction reducer, so would that mean your mount of the heatsink or water block has tighter seal? would be interesting to see if it creates a more even paste distrbution than a typical thermal paste. most thermal pastes only hit like 85-95% of the cpu heatsink/cpu direct contact. i wonder if this would achieve closer to 100% but then again it may have no active heat transfer capablity. i simply have no idea.

i don't think i'd risk it personally... i don't know enough science to do this Frankenstein project.

actually thinking about it now... the viscosity is probably too high since it is technically a grease... so it will leak everywhere, and lithium is good for heat transfer i think especially in paste form??? but again viscosity too high so it will leak and fry the mobo... unlike conductonaut which is prob less viscosity.

this is my thoughts anyway, i have no idea. if anyone has some ancient gear they don't mind that dies, would be neat to run some benches, a control study of traditional mx-4 or mx-5, then change to this grease and tilt the mobo around, see what happens. LOL @crazyeyesreaper this could be a fun experiment. i don't think anyone has ever tested this before. lithium technically speaking should work well, but I don't know what its rating is compared to conductonaut as far as heat transfer goes.

I know it is not used as bike chain grease, it is not long lasting. Comparison with WD40 is also not helpful since both are not okay. Usable stuff need to have long polymer chains. For instance teflon is not good due to this reason, too. There are few thermal mediums that work, interestingly Intel has been attempting to install paraffin as a phase changing paste, it has a close enough buffering melting temperature.

is it not long lasting because it is expose to air? as a paste with say a silicone sealant around the heatsink and cpu (again will never test this cause i don't want to ruin my gear LOL) it would not be exposed to air anymore. would that make it last longer, or is my thought process incorrect?

I'm just applying my bike expertise. Waxes evaporate even less than greases, so if you are going to apply something to, say, a fan hub - better lubricate that bearing that doesn't attract dust. That definition fits waxes, imo.
PS: not the regular cheapo waxes that are like teflon. Like... some... heavy wax "paraffin" though dunno how, or whether feasible.
Don't touch what you cannot fix. Go for the heaviest, least evaporative grease. I used calcium grease on an Adda fan, but wouldn't consider it great advice to be honest.

yeah it rules out anything exposed to air. i will agree there, still leaves open the cpu/heatsink sealed question. I also have no idea if it eats other metals, like conduconaut does with aluminum... so yeah just too many unknowns to risk it. conductonaut has already been shown to mainly only be useful in laptops anyway, so i guess this entire thought is pointless. bleh

Your question hit a common note since good greases are also solid candidates as pastes since they don't evaporate. Though to use waxes as paste correctly, you need to have a sealant around the cpu like how they apply liquid metal from factory.
I didn't go into dry lubricants(like graphite dust) since they conversely accelerate friction and require frequent maintenance. Only crazy people use them.

yeah if something doesn't have longevity to it its pointless imo. maintenance free is the name of the game imo, which is one reason I admire MX-4 and MX-5.

Someone here can correct me; lithium grease is for lubrication so it would not be useful as a thermal grease, or for coil whine.

WD-40 is a terrible lubricant, so most anything would be better.

For fans one might use Mobile 1 fully synthetic grease, although I actually use fully synthetic engine oil myself.

Now I do used silicon oil on computer connectors, but it is not a great idea for switches.

Greases in general aren't fantastic for motor lubrication. They're too thick in that application. Oils more easily get where they need to go. I don't usually consider most fans to be worth the trouble, so haven't dug into it thoroughly, but sewing machine oil has been suggested more than once.

Ain't gonna do crap for coil whine.
 
In my laptop lenovo t420 that is very hot generally, with arctic mx-5 after 20 days i had 90C (and under the heatsink the paste was watery) i replaced it with deepcool g40 and the results after 20 days is 79C.
Its seems at least for me that mx-5 is better from mx-4, but for small bare dies is not good enough.

That's an interesting proposition. I've never considered lithium grease as a TIM. The known chemistry suggests a solid maybe. I'm willing to give it a go. Gotta go get some in a tube first. All I have is a spray can and I don't want to waste it.

That depends a lot of the formulation of the suspension material.
For fans one might use Mobile 1 fully synthetic grease, although I actually use fully synthetic engine oil myself.
For fans I combine dielectric grease with a 20W40 synthetic oil in a 50/50 mix. Been doing that for decades to repair/service fans. Always work a treat and I rarely ever have to service that fan again.
