alphacool eisblock aurora acryl gpx-n rtx 4090 reference with backplate

The Alphacool Eisblock Aurora Acryl GPX-N RTX 4090 with Backplate (Reference) is a GPU water block for Nvidia Geforce RTX 4090 graphics cards built on the Reference Design board. The Inno3D iCHILL X3 and the PNY XLR8 Gaming Verto Epic-X are two of them. It cools the card with a chrome-plated copper cooler under an acrylic top, and the black aluminum backplate is in the box. It does not fit the RTX 4090 Founders Edition: for that card Alphacool names its Eisblock Aurora Acryl GPX-N RTX 4090 Founders Edition with Backplate (Art. 13456).

Alphacool adds two notes to this list. On the PNY GeForce RTX 4090 the rear part of the PCB is not completely covered by the block, which it says has no negative effect on the cooling performance. Inno3D uses two different PCB layouts: check the serial number of your card, and if it looks like 32-879-xxxx8xxxx, the card is not compatible with Alphacool's water blocks.

The block was designed for one PCB layout, and card makers sometimes revise a board so that a cooler no longer fits later models. Before ordering, compare your card and its PCB number with the pictures in Alphacool's GPU configurator, or look it up in its compatibility list for Nvidia cards. Alphacool's other blocks for the same board are the Core Geforce RTX 4090 Reference Design with Backplate and the ES Geforce RTX 4090 Reference Design with Backplate.
