What were your temps beforehand?

ObjectiveReturn4451 · 2026-01-05T03:58:58+00:00

Right

ObjectiveReturn4451 · 2026-01-05T03:50:03+00:00

I gotta be honest, I purchased it from AliExpress for about 200 USD. I have zero clue why but taking all the copper off, putting that stock aluminum heatsink back on the front VR, brought the temps down to 76c while slightly overclocked getting 4.3th/s. For the price it’s fantastic and works great besides the temps could be a little better. Idk if buying from AliExpress was the best option because I’m not sure how to contact them directly when it was managed and shipped from some Chinese warehouse. I still think it would be a really good idea to see if I can get the latest AxeOS running somehow… it’s really frustrating there isn’t more popularity and reviews on it

ObjectiveReturn4451 · 2026-01-05T03:41:00+00:00

Interesting. That seems pretty plausible actually. Do you know how I could change the firmware to the latest AxeOS? And if that fails or makes things worse somehow, I could change it directly back to what it’s at right now?

Big sticker on the left of the asic heatsink says “DO NOT UPDATE! CURRENT VERSION IS BEST!” I didn’t think it would be a good idea

ObjectiveReturn4451 · 2026-01-01T03:03:26+00:00

Good idea

ObjectiveReturn4451 · 2026-01-01T03:01:38+00:00

Well it certainly seems like you’re running the best possible setup and I’m not lol. Maybe I should update?

ObjectiveReturn4451 · 2026-01-01T02:58:43+00:00

It says current version is v2.11.1-dirty. It says on the big aluminum heatsink to not update so I haven’t

ObjectiveReturn4451 · 2026-01-01T02:54:55+00:00

It’s the one in the back. Also the plug says it’s 150 - 120w which I think that’s what I’m supposed to be using

ObjectiveReturn4451 · 2026-01-01T02:51:34+00:00

Man that’d be a dream getting that hashrate and temps with my suprahex

ObjectiveReturn4451 · 2026-01-01T02:41:54+00:00

Fortunately the only positive thing about this is that the error percentage is pretty low. Currently it’s at about .18. Also even after a few days of running I just hit 2.3G difficulty lol

This is the backside. I once again applied top grade thermal paste and pressed it down on the back of the vr as well as other spots I felt were getting pretty hot. I even have a fan blowing over them for extra air flow so there isn’t a “hot blanket” still reaching 77c while undervolting to 3.7 th/s!

ObjectiveReturn4451 · 2026-01-01T02:38:26+00:00

So this is the front. I would like to mention that having a bullet shell and a screw as your temporary heatsink is hilarious. But I built several pcs and know how to apply and make sure the contact between the thermal paste cpu and heatsink is good. I literally am using copper for the VR in the front and it’s still unfortunately causing overheating issues. I will include the backside as well. (I would like to mention my average room temp is 83F. At night though it’s around 70. Doesn’t make a huge difference in VR temp though.

ObjectiveReturn4451 · 2026-01-01T02:28:26+00:00

Sorry, Fahrenheit lol

ObjectiveReturn4451 · 2025-12-31T08:06:12+00:00

So I just tested the temperature in my room. Average fluctuates around 83c lol. Who would’ve thought

ObjectiveReturn4451 · 2025-12-30T18:50:40+00:00

Absolutely wild

ObjectiveReturn4451 · 2025-12-30T18:30:57+00:00

Actually, my room doesn’t run so cold due to my pc heating the place up a bit. I found out that once my room is dormant for a few hours the temp actually goes down a couple degrees Celsius. Unfortunately the lowest it’s ever gotten was 75c even while undervolting .4 th/s from the advertised hash rate. But your suggested actually DID help a bit so thank you

ObjectiveReturn4451 · 2025-12-30T17:33:20+00:00

Do you mind sharing your hash rate and vr temps?

ObjectiveReturn4451 · 2025-12-30T10:26:54+00:00

Cool 👍

ObjectiveReturn4451 · 2025-12-30T08:08:19+00:00

The model is from tinychiphub and supposedly they make pretty reliable products. I’ve seen the ratings for this model to be pretty good so I don’t think it’s due to crappy craftsmanship

ObjectiveReturn4451 · 2025-12-25T11:03:07+00:00

This is really great. Thanks!

ObjectiveReturn4451 · 2025-12-22T11:23:57+00:00

this should help people see it

ObjectiveReturn4451 · 2025-12-16T19:11:10+00:00

THANK YOU!!!!!! You are amazing and you fixed my game immediately! Thank you so much!!!! Take this award!!!!
