Наконец-то дошли руки сделать репаст или, правильнее будет сказать, смену термоинтерфейса на GPU.

Я уже то ли ещё на lor.sh, то ли уже тут жаловался когда-то, что у меня на высоких нагрузках на GPU вроде некоторых моментов в Clair Obscur: Expedition 33 или запуска инференса какого-нибудь FLUX локально просто напрочь вырубался десктоп.

Какое-то время я не мог понять, что происходит, но потом обратил внимание что GPU под высокими нагрузками неадекватно греется.

Под "неадекватно" я имею в виду 110-113 градусов Цельсия в горячей точке.

В общем, сегодня настал тот день когда я разобрал свою относительно старенькую RX 6800 XT, почистил от старой пасты, которая "убежала" и вместо неё поставил интерфейс с фазовым переходом.

На удивление управился во много раз быстрее, чем планировал. Сорок минут сборки, чистки воздухом и спиртом, замера чипа, вырезания термоинтерфейса, его установки и сборки всего этого обратно.

Результат - отличный, лучше, чем я ожидал.

Под нагрузкой в игре цифры такие:

Было:
GPU Core: 91C
GPU Hot Spot: 113C
Power: 280W
Fan: 1990 RPM

Стало:
GPU Core: 67C
GPU Hot Spot: 83C
Power: 285W
Fan: 1715 RPM

То есть, уменьшились и абсолютные температуры, и дельта между "средней температурой по больнице" и "горячей точкой".

Вместе с этим расслабился и вентилятор.

Операция "Грязь" объявляется успешной 🎉

Listen my good people, #PC people in the time of #inflation on components? Whatever you have #computer? You want an upgrade for little #money ?

Older #computer #laptop

Want to go faster?

#lowcost

Repaste! Repaste! #repaste

You can do it yourself or, have a shop do it! $20 to $50 dollars for 5% performance improvement! #REAL

#PTM7950 can make your computer faster, it can. #liqidmetal repaste? Maybe for your last three years on an older performance #gamer rig.

#linux (more complex) too!

A bit of a methodological error, my all core sustained on the CPU is 3.4ghz using stress. The numbers I reported were with #Ollama working a query. So I am 500mhz faster than spec with #ptm7950 phase change cooling. #laptop #AI #LLM #repaste

There can be quite a bit o juice left in older laptops.

I may be the first or only person to ever post here about the impressive #ptm7950 phase change TIM. I think anyone with a PC a few years old needs to know about it. (Some newer come with it installed.)

Booting is a busy time for a computer, on a cold start my laptop (2018 i7-8565U) CPU jumps to 62°C by the time I can log in, then drops to 30°C idle within minutes. Then if I stress it (literally: stress -c 8) it will only get back up to 53°C all cores at 100% after a ~1 second excursion to 72°C.

12°C delta below start up peak CPU temp, 19°C transitory spike starting stress that almost instantly abates.

I wish I had tested it before repasting it with #PTM7950, I'm curious.

I wonder how #PTM7950 compares to other cooling solutions in price to performance ratio.

I mean, I’m all okay with paying for a good paste, pad or sheet that doesn’t dry in 4 years. I’m not okay paying $50 for a square inch.

so i replaced the thermal paste on my ryzen framework 13 with one of those ptm7950 pad thingies. seems to have made kernel compilation stay at around 80c (it was 90-100c before). definitely seems like an improvement. not terrible considering it came from some random seller on amazon. i’m surprised framework/other laptop companies don’t ship something like this by default, maybe it’s too expensive idk. (yes i realized i probably could have gotten more of the old paste off, i tried ok?)

@BigMcLargeHuge What I meant with the Pi heatsink is that there's too much space between it and the chips it's meant to be cooling. I didn't realize this until after I applied the #PTM7950 and tried sticking the heatsink on.

Status Report: formerly angry, now miffed.

Turns out the heatsink I got for my #RaspberryPi4B has too much clearance for my #PTM7950. Found this out AFTER taking all the measurements, precisely cutting it all out, and sticking it on after multiple failed attempts.

Progress on the Pi has completely halted for the day. I'm going back to learning #hardwarehacking.

Here's the heatsink btw: https://www.amazon.com/dp/B091L1XKL6
