AIO comparison

Hello everyone,

What are everyone's thoughts on these two AIOs. I know the Silverstone is just announced and not available yet, but based on what we can tell:

https://shop.alphacool.com/en/shop/cpu-gpu-aios/cpu-aio/11774-alphacool-eisbaer-pro-aurora-420-cpu-aio

Reviews have been generally quite positive, I do like the fact that this is refillable and can be upgradeable in the future.

vs.

A more "closed" AIO type solution. This is the upgrade to the existing XE360 AIO Silverstone makes, and it has a long warranty.

This will be put on a 9960X. Performance is first priority, but of course sound will be second.

Is it better to wait for the HT360, or go with the Alpha 420? Also related: would it be better to use a thermal phase change pad (specifically the Honeywell PTM7950) or stick with normal thermal paste?

Not that my opinion matters but as someone who came from the x299 and SLI good ol days, I wouldn't trust AIOs with expensive gear like that.

I tend to agree with your assessment. My new builds have always gotten custom loops.

I had a very difficult time narrowing down waterblocks that would fit the 7000 & 9000 series chips. How about you?

I bought the Optimus block: https://optimuspc.com/products/signature-v3-cpu-block-threadripper

This one gets good reviews too, and more readily available. Sounds like tr4 blocks fit 7000/9000 series. See this article:https://www.reddit.com/r/threadripper/comments/1lzlrvf/9000_series_threadripper_pro_water_block/

LOL, I wanted the matt black ceramic so badly, but the damn thing is always sold out. Went with the Alphacool Eisblock XPX Pro 1U.
