IgorsLAB checked out the Corsair Hydro Series XG7 RGB water block for NVIDIA GeForce RTX 3080 and RTX 3090 reference design A quote from the article:

The second water block I tested was the Hydro Series XG7 RGB, a product from Corsair for NVIDIAs large Ampere cards. Interestingly, the interest of most manufacturers in detailed tests is now rather restrained, because especially the comparison series of the GeForce RTX 2080 Ti has shown very clearly that RGB and bling-bling do not.
