Optimus Foundation CPU Block - AMD

The case I'm using has a big opening on the back side of the CPU area of the motherboard. It's a BeQuiet 900 rev2. It's not really a case for a bling setup, I didn't know that when I bought it, but it's turning out to have a pretty clean look anyway.
 
\yes the Thermaltake view 7 that i Will be using for my build has the same, come to think of it, most cases do These days so forget my previous thoughts then, cept that idea re cable routing, lol!
 
i saw their prices. f**king insane. modern amd CPUs don't need NASA grade cooling. my gaming rig has an OC 3900X cooled by an EK supremacy evo, which was like $50. works fine. i used this same block on a 7960X, worked fine there too. my current workstation, the 7960X replacement, has a threadripper 3960X, using PBO with raised power limits (drawing 350W vs 280W stock). it's cooled by a $80 XSPC waterblock. again, works perfectly fine.

i don't know how many people they think will shell out $135 per block. if i was going for aesthetics , i'd go for watercool. no matter how i look at these blocks, they just don't appeal to me.

watercool? Got a link?
 
Well that was a heck of a quick read and catch up on this thread!!

I'm currently considering an air cooler for my 3900X or to go out and grab some new water cooling parts cos, I'd like to think that would be the better way forward.. Considering a decent air cooler (to replace my 14D that's just sat on top of the CPU right now) is going to be about the £80 mark at best, CPU blocks are getting to be close to that or a little cheaper depending on what you prefer :)

I need to do a little saving up first and then I can try and get some parts. I have a case in mind for this project which I've had for ages and not used so, it's about time I got things in gear and got it sorted and up and running!! :)

The block does look nice and is one on my possible list :D All the results seem pretty decent in the thread as well, so I'm eager to try I think :)

Which case out of interest?
 
Oh I bought it back in 2016 I think... It's a Thermaltake WP100 I think the model is, it's one of the knock offs that look like a Caselabs case that costs a 1/4 of the price :)

Time for some 560mm rads in there I was thinking.....
 
Looks a bit of a beast

It is, funnily enough when Isabelle was 4 years old, I had a picture with her sat in the main part of the case :roll: :laugh: I just hope I have enough cooling capacity.....
 
What can it fit? You mentioned a 560, so I'm sure that whatever you throw at it will fit in it

I'll be putting a few things in my project link if you'd like to take a look sometime, link is in my signature :)
 
Just so that no one else makes the same Costly mistake that I have made, AM4 backplate thread size is NOT M3.5. As in it is a 3.5mm diameter thread, but Not a standard metric pitch, seems to be 6/32 thread

oh wow, if you don't know about watercool and their "heatkiller" series then you've been missing out. they are consistently rated as the best performing blocks on the market by every review i've seen

Oh yeah know heat killer, just wasn't aware that was its full name

if what is being said about the latest Optimus blocks, then they won't be saying that about heatkiller in the future.
If you don't know that one check out threads on here and elsewhere
 
See that EK are now adding a bow to their coldplate as well now.
Looks to be the next 'in' thing

FYI, EK (and others) have been doing it years before Optimus even existed. Its nothing new.
 
Yet reviewers are only now mentioning it. Either the makers need to up their marketing, inform reviewers, or something then, as I've Not seen that mentioned on any site before, I could have missed it I guess but on Every makers site that does that?
 
Hey "lorry"

You posted that your block arrived back on Feb 15th...

Have you had a chance to mount/test your AMD Foundation block yet? Any thoughts/results as compared to what you were previously running?

I've not as yet mate, nor will I for a while sadly.
Had some personal shyt come up that needs attention first.
About as bad a timing as it can get, new case, new block, can't touch for now.
 
Hi,
Too bad I've really grown into my Intel foundation so I'm sure when ever you get a chance you'll enjoy yours too.

3950x listed for 699.99 locally too :-)
 
It's running!

Some were concerned that the Optimus block restricts flow, I don't see that as a problem at all. I have the whole pump curve under 45%. At 100% CPU load the pump runs about 2180rpm, the CPU runs 71C, and the water out of the block runs 30C. I could turn the pump down even more.

I can see the actual flow from the waterblock in the internal tube of the upper water cylinder. It's very low flow as I type this. The water in that internal tube is T_SEN1 on the no load screenshot below;

Right on! Nice looking build there as well, cool to see our reservoir with clear coolant, really clean :D And, yeah, restriction isn't as big a deal as some would think. After all, the numbers speak for themselves :)
 
If I can cool a R9 3950X at under 2200 pump RPM during a 100% CPU stress test and the water out of the block is 40 degrees less than the CPU, there's not a restriction problem. I'm in an industry were we use various water to water and water to air cooling systems and hi velocity is not a proper cure for cooling problems. We've cut down impeller diameters to slow down flow to improve retention time and cooling.

We started with the pump curve topped at around 80% and dropped it to 45% during stress tests without the CPU temp going up at all. It's always run 70-72C.

The pump will run 4740 rpm!

I'm waiting for my Foundation AMD block to be shipped but seeing as I'm currently furloughed I have plenty of time to run before and after tests for those wanting the comparison. If anyone has specific tests they want running please let me know.

The (what I think are) relevant parts of the system I'm using for this are a 3950x running on an X570 Aorus Master, an XT45 360 rad with NF-F12s in push, EK Kinetic D5 res-pump combo, and most importantly an Eisblock XPX CPU block.

Judging by the max RPM, I’m guessing it’s a D5 or DDC pump. If you have to run the pump faster than that, then you have a problem. I’m running my D5 pump at around 2000RPM. The water goes through two 360mm rads, a threadripper block, an RTX 2080ti block, and (this will sound crazy) but a block that cools my intel X550-T2. All are middle of the road water blocks. Nothing fancy here. See system specs for exact parts.

I had to put a block on that NIC because the factory intel cooler can’t keep it cool for longer than 5 minutes of continuous use (go figure).
