i am highly interested in the SYY 157 paste.
seems to be a very decent paste for direct die applications. anyone here tried it before?

Finally got around to finding a candidate for mx-6. My 1st gen XB1. In hindsight I probably should have spread it but so far the fan is barely ramping up much if at all so the x-clamp plus 4 screws must have done the trick to press it down and spread it out.

You should spread the paste on lidless BGA chips to ensure full coverage.

Currently on it
3600 and 3070FE in a NZXT H210i
Literally the best paste i've used to date. Beats everything i've tried (NT-H1, 2, mastergel pro, MX4, gelid gc extreme, kryonaut, hydronaut, ic diamond and so on...)
Haven't tried TFX yet. Heard they come out of the same factory. Lowest temperatures i had and lowest hotspot difference (9 to 11)
Spread it, let it rest 20m and put it back on. For the price it's just amazing.

that sounds like i have to buy a tube
i heard people saying that the 157 lasted over 1 year on a GPU without even degrading by a single °C.

i don't even care that much about performance but pump out resistance...
This is NT H1 after less than 4 weeks! on my 6800XT.

Looks like a cool painting, but not something I want to see on a GPU core.

I tried NT-H1 when D14 was a new cooler. It did the same to me, and I swore it off ever since.

Hi,
I've never had any issues using it on water blocks cpu or gpu's.

Hi,
I've never had any issues using it on water blocks cpu or gpu's.

probably because the waterblock on the GPU is very thick and barely expands under heat. (plus the GPU temperature is much lower)
it just pumps out after a couple thermal cycles. (around 70°C load temp for ~100 hours of load = my pictures)
on a CPU with an IHS that's not a problem.

 

[igralec84]

I'm currently using Kryonaut Extreme (switched from the normal one) and it's very hard, almost like bubble gum and i used the pea method that i always use.
Not really sure it spread evenly but the temps seem normal. Will maybe check one day but it's a hassle as i don't want to move/unplug the 4090 that is like 2mm away from the Z73 CPU block. Had to undo all but one screw holding the vertical mount so it lowered just enough to undo the bottom two thumb screws and replace the CPU

Hi,
What were you doing gpu mining ?

Highest gpu temp under heavy oc'ing I've ever gotten is roughly 45c+- obviously not 24/7/365
Cpu well my comfort max is 95c at max clocks so I do push the shit the system I've just never seen nt-h1 evacuate the area like you showed.

 

[GerKNG]

under water...
not with the stock cooler.
6800XT Aorus Master, Overclocked (315W Limit)
70°C Edge, 85°C Hotspot on average. (pump out after 4 weeks) = 75°C Edge, 105°C Hotspot.
it's a thin copper plate that expands a lot under heat and the chip runs hot anyways.
your CPU die is under a heatspreader. that prevents basically any pumpout since you have this massive chunk of nickel plated copper on top that gets barely 60°C warm when your CPU is already running at 100°C.

Thermal Grizzly is using the same approach Glorious does with their mice. They buy a lot of paste from some factory I don't know, rebadge it and rip you off. I'm using the words rip off because their paste cost a lot more than alternative similar formula, such as TF8. For the mouse example, most honeycomb mice is made by a company called Ironclad.

In this case, when you look at the syringes and the spreaders, packing, everything... you'll find out that it all is more or less the same thing. Off my head...

Grizzly, Alseye, Thermalright, Halyzinye and the bunch of others depending on your region, such as Pullwark. These are the top levels of conductivity TIM. It doesn't include the TIM outside of packaging that looks like a syringe and a head that attaches to its top needle point.

I have not seen any mx6 yet in Canada. Any consensus on what the best stuff is for longevity and pump out?? I’m looking for something that will last reliably for 6 years minimum before repasting.

 

[Franz]

Better than GD900?

Yes, it seems more stable temps and lower spikes

You put enough on there, it should be good.

I thought as much, unfortunately being a locked down console, I can't report on before/after temps but the console plays fine and it blows out nice hot air as it should.

 

[freeagent]

Lately I have been using TF7, it is what comes with Thermalright coolers. It's pretty good stuff I would say. I was using SYY-157 previously, and it too is quite good. I am going to have to order another tube of TFX because I keep saying it's my favorite, but I used it on coolers that I no longer use, and only had the one tube

Is it blowing out warmer air than before?

 

[Shrek]

It can't

Let's say one has a 100W source, no matter how bad the TIM, it still outputs 100W

?!? Who were you responding too?

 

[Shrek]

Your question "Is it blowing out warmer air than before?"

Although there is a proviso, electronics actually produces less heat when hot; transistors are sometime run without too much cooling to take advantage of this effect.

Ah I see. You didn't use the "Reply" function so it didn't automatically seem like it was a direct reply. Anyway, thermal dynamics apply. If the TIM is doing better, the heat output will "feel" cooler as the heat is being transferred to the heatsink and then to the air more efficiently. It's kinda counter intuitive, because one would think the if the TIM is doing better more heat would be vented, and while that is true, the effect is that because the heat is being transferred better the overall effect is that the thermal output of the system will be reduced because the heatsink can to it's job better and as a result doesn't warm up as much because it has an easier job of transferring that heat to the venting system.

A poorly performing TIM would transfer heat slowly and thermal saturation would be a thing, resulting in the air flowing from the venting system being hotter. With electronics, more heat always = bad, less heat always = good.

So the above question is valid for those reasons.

 

[jayjr1105]

I can't answer that. It was re-pasted a few years back with MX2 or something I had lying around. Only reason I re-pasted again was because I was already inside it to replace the hard drive and I was itching to try MX-6 on something. It was performing just fine thermally and probably still is. Had I known MX-6 is much thicker, I would have spread it but I trust the clamp and heat did it's job to spread it out.

Not here to make trouble, but any TIM would transfer the SAME heat for the same CPU (conservation of energy), except for the proviso given above.

However, the bad TIM will have the CPU running hotter.
