Asus 4070 dual oc repaste results

[Taraquin]

I've had my card for 2 weeks now, but the hotspottemps annoyed me. From day 1 they howered around 20-21C above gputemp. I decided to repaste with MX-6. Card is run undervolted at 2655@915mv and +1250MHz vram.

Stock with fans at 30% unigine superposition:

After repaste:

Re-ran tests several times. Gpu-temp dropped by 2C, hotspot by 5C.

Then I tested mining with Nicehash with fans at 50%:
Stock 61C/82C HS
Repaste 59C/76C HS

With fans on auto the stabilized at 49% stock, 41% after repaste with gpu-temp at 60C in both cases, but hotspot at 83C stock and 77C repaste.

With mining and fans at auto I get lower noise and 6C lower hotspot

Overall I'm satisfied with results

Wish i could do that without loosing the warranty. Depending on how games like STALKER 2 will run on it, i will keep it for a year or more. And if i still have it when the 3 year warranty expires, i will repaste it too and maybe change the thermal pads.

Hmm, I see no reason to repaste a GPU with a 66 degrees hotspot and voiding the GPU's warranty in the process....

In mining it was up to 83C and it kept rising week by week. Part of the die barely had paste on it so I see the reason why. Where I live I still have the warranty intact

The last few days delta temps has increased and is similar to before repaste (delta a bit above 20C during hard load). Avg temp is still lower though. I disasembled and the paste had pumped out just like the stock paste and certain areas in the midle had little paste. I ordered Thermalright tfx extreme, it is said to be much 'harder' and dont pump out.

Lesson learned: I need a 'harder' paste that dont pump out.

 

[Keullo-e]

Too much paste IMO.

Yeah, I had less on with the repaste, shouldn't increase pump out though.

that's still paste making contact everywhere, paste isn't magic. if your getting normal temps just be happy.

 

[Taraquin]

I tried lower mounting pressure, see if that works.

Ambient temp is rising so hotspot tends to go above 85C which causes throttling in mining even with fans rinning quite high and powerlimut at 150W :/

MX-6 is a garbage tier TIM, just move on and don't waste your time with it. Plenty of proofs around. Two different GPUs and CPUs had the same pump out issue from my own experience.

Edit:

And when you consider that by just opening your GPU for a repaste is also leading to a large possibility of destroying your GPU thermal pads, it's even worse. And I've put the damn thing on everything I had at the time. A real jackass, non the less.

Pads are good quality, no problems. On cpu MX-6 performs very well, no pump-out, better temps than MX-4. I have repasted many gpus, cpus and notebooks over the years with kryonaut and mx4, no pump-out issues until now...

MX-4 8g tube I have for years (started separation inside), still performs better than MX-6, and never saw it pump out from anywhere. Probably will stick to the Kryonaut for the CPU and Conductonaut for the GPU in the future.

IMO, GPUs aren't worth 'cracking open' anymore (within warranty) unless, there's a flagrant and easily corrected issue (or, were purchased with the intent to watercool).
Unless mis-manufactured, the factory TIM should be good for years.

On TIM:
Yes, 'pump out' is real. MX-4 was decently great paste but, obsolete due to thermal density; MX-5 and MX-6 have had issues.
Note: I have seen MX-4 'pump out' on 2 or 3 Vega 10 cards. I'd still rank MX-4 as 'better' than its successors, sadly.
Honeywell PTM7950 is typically considered 'the best' for non-migrating TIM. Admittedly, It's more of a PITA to get and apply than a paste.

As far as warranty:
I'd have 0 qualms with either heat+xacto'ing the 'warranty seal' or replacing it w/ AliExpress stickers. In the US, this is 'maintenance' and *is* covered under the Magnusson Moss Warranty Act.
Those stickers are supposed to be 'meaningless'. However, we all know that law is almost entirely ignored.

I have only repasted 4 of the 20+ gpus I've had for the last 30 years. All due to cooling issues, the 3 others resolved easy, this one not so much.

Is that vRAM thermal pad on the right from the factory, if so, what dose it cool, because there are no chips there ?

I'm not sure if this is applicable to modern cards but:
Have you considered a "washer mod"? Back in the day, more than a few cards greatly benefitted from teensy bit more clamping force.
IIRC, even some of the (recent) AIB partner 6900XTs had 'mounting pressure' issues.

Related issue:
You probably should replace the pads. As far as I'm concerned, thermal pads are 'spent' the moment they're compressed.
I'm an advocate of thermal putty, TBQH. Just, be careful not to over-compress it to start; most putties aren't 'springy' and will not 'pop back' after being squished out from a mis-mount.
Regardless, even after dismount, you can 'roll it back up' and re-use the stuff.

Basically, AIB use(d) same cooler on several models (inclu. ones w/ fully-populated PCBs)

I guess I'm lucky with my MX 6 on both of my CPU and GPU, repasted them months ago and the temps are still all good/same as after the repasting.
I prefer the thin layer on the IHS/die method instead of dots or whatever and so far I'm yet to experience pump out on any of my CPUs/GPUs with various pastes over the years. 'MX 4/GD 900/Whatver my ID cooling CPU cooler came with'

In my case my Asus TuF 3060 Ti developed a completely dried out factory paste issue after a few months I got it 'second hand GPU' so I took it apart and first I've repasted it with GD 900 and used it with that until I've got my MX 6 and both worked just fine/still does.
The screws on this card are spring loaded so I couldn't possibly mess it up just tightened as much as they allowed.

Last card I repasted was a 2060, that worked really well, but 4070 cooler may behave differently. Vram temps are fine after repaste, good quality pads, but maybe not the most efficient. Havent considered washer no, but that will require me to change pads aswell :/

All of my applications were done with a scalpel blades with aim of making a thin as possible layer. But I guess our tubes have a different ingredients or w/e. I'm kinda tired of this. I just wanted to raise an awareness how bad it can be, and what can be expected.

MX-5 and MX-6 have both been reported to have separation and pump-out issues. As far as I can tell, no one 'in the tech influencer-sphere' are even touching AC's MX pastes any longer.
It's not a 'rare' problem.

Considering that MX-6 was supposed to 'fix' MX-5's problems, I can only assume there are some 'production/manufacturing' level issues. Tube-to-tube/batch-to-batch constituency may vary (seen this even in caulking)


I've been recommended SYY-157 and Shin-Etsu’s X-23-8117.

I'm not opposed to trying out 'industry, bulk' TIM (SYY-157)
and
In the past, I've had extremely good luck w/ Shin-Etsu, and would 100% 'trust them' to competently engineer a paste for ODM/OEM and Industrial use.

Yes, i know, but why put a thermal pad if there are no RAM chips to cool them with ?

Its fine, thats why I've mentioned that I guess I'm lucky cause I did hear about MX 5 having issues so I've skiped that and kept using MX 4/GD 900 and then gave MX 6 a try.
Honestly it did not really improve my GD 900 temps but I just did it cause I was curious + no one can really tell how GD 900 works out in the long run. 'My GPU is really easy to take apart so I was like eh whatever'
What surprised me is how bad the factory paste was, I mean drying out is one thing but the paste on my GPU was literally turned into a thin layer of dust/effectively it was running with no paste at that point.

Luckily the pads are still in good condition on my card even after taking it apart 2 times but I would rather not do it again unless the temps get out of hand or something.

It really does pump out though. I posted about the same issue with MX-6 on my card recently as well. In my case, it absolutely trashed the hotspot temperature

Too much paste IMO.

better to much than too low.

I did another repaste 23.03 but used medium mounting pressure. So far hotspot delta has kept at 16-18C, no rise, looks better I also ordered ptm7950 pad (Nvidia uses it on 4090 FE) and thermalright tfx extreme. Testing incoming whrn I get them
