Anyone tried OptimusPC water blocks? CPU blocks I'm interested in. Any recommendations/comments?

I was using one on my x299 board with a 9980xe and a 10980xe. So far in my opinion best cpu block I ever used. Of course now that I switched to amd my optimus block is not even being used any more and just sitting on the shelf.

Thanks. I read one review which said their mounting system leaves something to be desired, but that may have been an older review (and they didn't elaborate on what their gripe was). Any comment on that, or is it just standard fare like an EVGA AiO cooler (for example), which is no problem at all. From all other reports I've seen, the performance is excellent.
 
 
 

 
Great, thank you. The Signature V2 is likely the one I'll grab.. a little pricey, but beautiful looking in a 'brutalist' design kind of way. Machined from a single 3lb block of brass, nice. I'm looking at the raw copper cold plate finish.
 

I have 2 foundation blocks and they are great, I wouldn't bother for the signature it is not worth the money.

just book an Threadripper waterblock, wating to try

Yeah that's the one I have, it's for sure heavy, I should sell mine and get it over with since I switched to amd system.

Let me know if you decide to sell it, although I'm wondering what AMD will have to offer with their upcoming CPU release..

I have the AM4 block.  When I ordered it direct form Optimus, Optimus listed it on their site as in stock, which was incorrect.  I ended up waiting about 10 weeks for it to arrive with multiple excuses and missed delivery and shipping dates.  
 
After it finally arrived, I did back to back testing in the same system and at best it cools my 3950X 1.5C cooler than the $70 Corsair universal XC7 CPU block.  That's during a 4.3 GHz all core overclock when the CPU is drawing about 280 watts.

I ended up buying SpareTimePC's Signature V2 which I just received. Due to the unavailability of any 30XX GPUs, I have put plans on building a loop on hold, but the Signature V2 is pretty impressive (and heavy!). I believe the Signature V2 is a step up from their Foundation blocks - and it should be for the price. Δ1.5°C for the Foundation block is nothing to sneeze at.

I expected more considering all the claims others were making about its impressive cooling performance due to its AM4 specific design of the water flow.  A generic block that was half the price and not designed for the AM4 chiplet design came within 1.5C at ~280 watts when compared to a block designed specifically for AM4 is even more impressive.
 

With modern blocks, they all get within spitting distance of each other with thermal performance. What differentiates them is the quality of craftmanship, EKWB (which I always buy) started out as a high quality brand but I've heard noise of their nickel plating flaking for some people. With Optimus, it sounds like they put in extra effort and use higher quality material/processes when building their blocks which would be a good thing if you plan to keep a block in your loop for a long time. Sadly I require RGB for my blocks so Optimus isn't an option for me yet.

There is a new German brand TechN which looks like they compete well with the new Optimus but have RGB included so it may be worthwhile to watch them.
