XIREX Stealth Waterblock

Test Results

Test Results
Pressure vs Flow chart
Temperature charts
We can see from the pressure vs flow chart that the Xirex Stealth is certainly more restrictive than the XSPC X20 Delta that it was tested against. That being said, the Stealth managed to perform better than I'd expected when we ran the actual cooling loop testing.  If Xirex were to include some micro-channels in the base of the Stealth and relieve some of the restriction present, we may see a significant reduction in the defecit between the two blocks. Regardless, the Xirex Stealth block performs quite well as it is, but just remember to factor in its restrictive nature when designing your loop by looking at the beefier Laing DDC Ultra instead of the Pro.

Xirex are relative newcomers to the water-cooling scene and their Stealth Waterblock recently stopped by for a visit. Boasting one of the lowest profiles I've ever seen in a waterblock, it certainly has the looks...but can it hold its own?

Seeing the vertical size I thought it'd suck. Thats really good to see manufacturers not going for the norm and still having the firepower to compete.

Nice review as always
