I’m getting a HDMI cable tomorrow to try and see if that works, heard I’m some cases it does. Probably won’t be going ASUS next time for a build. I don’t understand because nothing has changed :/
Could be a problem with the PCie x16 slot itself - happened to me when some paste went in !I’ve tried bothe the 3090 I’ve messed around with and an older 970 that I know works both caused the vga light. Using a 12700kf so no I gpu either. Assume it’s a fault on the board as I’ve tried everything else. Appreciate the help
Hello there,Hello there,
I've bought an Alphacool Eiswolf 2 for my Asus ROG Strix 3090. While my CPU temps were lowered by quite a bit, I still noticed a very high Memory Junction VRAM temperature of 90c+, even running up to 100c when playing very demanding games at Ultra / custom + (e.g. RDR2).
I decided to re-pad the chips, and when I removed the waterblock from the GPU, I saw what the problem was:
The 1 mm padding that is supplied with the AIO for the 'front' side of the GPU is not thick enough, and is not making contact with the VRAM:

Image 2: No imprints of the VRAM whatsoever.

Image 3: No imprints for the VRAM.

Image 4: No imprints for the VRAM.
So, above are the thermal pads that come with the Alphacool Eiswolf 2 AIO, and are 1 mm in height.
I've replaced these with 1.5 mm padding and re-seated the waterblock. This time, you can clearly see the VRAM making the imprints. I've also taken care to make sure the height was correct, so the GPU main processor and the mosfets etc are still making contact with the block when using 1.5 mm VRAM padding:

Image 7: Clear VRAM imprints with 1.5 mm padding.
View attachment 3623
Image 8: Clear VRAM imprints with 1.5 mm padding.
For the record, the VRAM on the backplate was showing correct imprints, and these are 2 mm (as supplied by Alphacool).
Another thing I noticed, was that Asus is padding the VRM chips also, but AlphaCool is not supplying these, or mentioning this in the guide.
In fact, there is a rather large 'gap' in the waterblock, so the VRMs are not even touching the block:

I've filled the gaps with 2.5 mm padding, making sure that the VRM is now also making contact with the block:

Image 10: Clear imprints for the VRM.
The results.
The difference after applying the correct padding is amazing. Mind you this card is running a slight overclock @ +165 gpu mhz & 112% TDP.
Before (using the supplied padding by AlphaCool) while running heavy benchmarks (Unigine SuperPosition, RDR2 @ Ultra+):
VRAM temperature: ~90 - 98 degrees.
After repadding (using another brand, but thicker padding, now VRAM making contact):
VRAM temperature: ~60 -66 degrees.
This is a whopping 30 degrees celcius difference in GPU Memory Junction temperature. Also, the VRM is now ~10 degrees lower (from ~44 degrees to ~34 degrees).
@AlphaCool, I hope you can make adjustments to the way the 3090 Strix is currently being padded.
Also, could you contact me in private to discuss a compensation of some sort?
For the record: I'm VERY happy with the Alphacool Eiswolf 2. Compared to the (not so bad) stock coolers delivered with the Asus ROG Strix, it chewed off a large piece of temperature, and obviously it's running extremely silent. I'm hoping very much that an active backplate will be devised soon, so I won't have to mod it with my own heatsinks and fans
Hope this helps anyone who wonders why their Memory Junction VRAM temperature is still rather high with this AIO.
For all here who have problems with the pads. Write to our support. We know the package problems with Nvidia and we know what kind of pads you have to use to make it work as good as possible in the end.
It makes little sense to buy any pads with the wrong heights or the wrong consistency. We have different pads with different consistencies to compensate for height differences. All the support needs is a picture of the prints of all the pads. From this we can determine from our experience which pads would give the best result. If you can provide us with an invoice, no matter from which dealer, we will send you the pads free of charge within the warranty period.
Hi, we can't say until we see the pad prints. Please upload a photo of the pads for the cooler & the backplate after initial assembly here. Only then can we see if your card is affected by the package problem.Thank you very much for your support, I wonder if you could help me on this one:
I will receive my Alphacool AIO next week for my Zotac Holo AMP 3080, I will be installing copper pads, I wonder if you know if 1mm is enough or I should go 1,25 or 1,50 for this Zotac, I'm not really sure about the problems with Nvidia and if they affect Zotac's cards somehow
Thanks again!
Thanks for replying Thomas,Hi, we can't say until we see the pad prints. Please upload a photo of the pads for the cooler & the backplate after initial assembly here. Only then can we see if your card is affected by the package problem.
I can't hear anything, just wondering if reducing the speed % can increase its life spanCan you hear the pump running at full speed? I'm guessing you can't hear it out of the closed case unless you put your ear right up to it, right?
A pump that is constantly regulated is clearly more heavily loaded. If you are bothered by the noise, it is better to fix the speed. However, then the performance also drops.
Thank you so much sir, I am so very surprised with the results and this is with a temperature room of 30ºC, the summer is really aggresive in south-east Spain, so it is like +3ºC only on the GPU lolThe temperatures are very good even on the memory and hotspot. Good job you have done really.

Pentru înregistrare: sunt FOARTE mulțumit de Alphacool Eiswolf 2. În comparație cu răcitoarele de stoc (nu atât de rele) livrate cu Asus ROG Strix, a mestecat o bucată mare de temperatură și, evident, funcționează extrem de silențios. Sper foarte mult că o placă de spate activă va fi concepută în curând, așa că nu va trebui să o modific cu propriile mele radiatoare și ventilatoare
Sper ca acest lucru să-i ajute pe oricine se întreabă de ce temperatura lor VRAM Memory Junction este încă destul de ridicată cu acest AIO.
