They are fine with up to 110°C.
How thick? 1,5mm?Hell no, that's a lie! They are not fine at 110°C, they start throttling at 100°C. They suffer degradation on time at those temps.
Alphacool did a really bad job at cooling VRAM. They used bad quality thermal pads plus wrong thickness.
I replaced all thermal pads (backplate too) with 12W/mk ones and VRAM temps went from 88°C on gaming to 60°C. Mining Ethereum temps went from 110°C (reaching 77MHs) to 82°C (reaching 88MHs).
Clearly Alphacool design is not ok. Micron (GDDR6X manufacturer) state temperatures from 0 to 95°C.
Can you tell me what gpu do you have and what brand of thermal pads you changed the stock ones with please?Hell no, that's a lie! They are not fine at 110°C, they start throttling at 100°C. They suffer degradation on time at those temps.

I've a 3080 TUF Gaming as I said previously. I replaced all thermal pads:
I used GELID (12W/mk) for the 3mm and Thermalright (12.8 W/mK) for the others.
Whoever is affected by this will get help from us! Simply write to support (info@alphacool.com) and with the help of pictures you will be sent the right pads free of charge. Doesn't that sound like an acceptable solution?
They changed the specifications of those memory modules. 110 is no longer seen as acceptable rangeGDDR6X has much higher temps than GDDR6 (non x). They are fine with up to 110°C. So no problem here. We have also some 3090 cards here for our own using since.... well before the release of cards and they are always working under full load (renderings and things like that). We have no problems.
Ok...so you want me to drain all of my loop, disassemble my GPU / water block to make pictures and then I still have to "hope" you guys "confirm" my problem and send me some pads. Meanwhile I'm supposed to wait or go through the hustle of assebling and disassembling my stuff several times for a known problem (as you surely are aware, this is not the only thread mentioning this). This really does not sound like "Whoever is affected by this will get help from us!" at least not in a convenient way for the customer...
