Hello Alphacool team!
I would have some problems with an "Alphacool Eisblock Aurora Geforce RTX 4090 AMP with Backplate" block.
I wrote an email before, but I didn't get an answer for 1 week.
The story.
On 04/06/2023, I ordered a block (Nr.: B 2911121) for my card from Aquatuining.de.
After I got it and put it together I got high temps and it looked like the block was not flat in the GPU area.
I contacted my contact person (the order was made by email, as it was a company purchase)
Within a short time, it was replaced with another block. (F10491972)
Visually, this block was perfect. However, I also got high temperatures with this.
With the added pads, the memory was 42 degrees for both blocks under load, but the GPU was ~90 degrees, while the Hotspot temperature was ~110 degrees.
I disassembled and reassembled the block several times, nothing changed.
At that point, I started to guess that something was going to happen with the PCB, because I didn't think it was likely that both blocks would be faulty.
That's when I got the idea to try thermal pads of different heights. As a test, I replaced the factory 1mm pads with Thermal Grizzly 0.5mm pads, and the situation became much better. During the tests, the GPU is only ~42 degrees, the HS ~48, but the memory is 62-70 degrees depending on the load.
I suspect that the factory-made 1mm pad is too high for my PCB, so there is no proper contact, but the 0.5mm pad is not enough.
As a tip, the 0.75-0.8mm pad would be ideal.
But I didn't really find that. I don't have any problems with the factory air cooling, I get good temperatures with it.
Factory cooler AIR
Install thermal pad (1mm) AC block
Imprint 1mm pad:
Install thermal pad (0.5 TG)
WC konfig:
EK Velocity2
EK D5 Next
10/16 soft tubing
AC Supernova 1260
What can you recommend to ensure that the temperature of the memory is also perfect?
Is it possible to send me pads with a thickness different from the factory pad?
Thank you in advance for your answers.
