The Phobya CPU waterblock

[Eddie3dfx]

If this block dumps more heat into the water, wouldn't using a better rad and a more powerful pump lower temps even more??

Even if the cpu block was not better, a more powerful pump and specifically a better radiator would result in better temps.
I added a 2nd pump to the cpu and the results were the exact same.

pumping wise, no the pump would make little difference. Airflow thru rad, yep, but for fairness I ran fan speeds at the same levels, if I ramped up my fan speeds temps will be lower and be even lower if I slap my san aces on which I may try this weekend. Something else I wan to try is bare die cooling, this block is perfectly flat.

45c and 42c...wow thats a huge improvement...are they going to retail in the USA?

I'm guessing after Skinnee runs his tests and depending on how it runs for him Petra, Sidewinder, Jab, etc may start carrying them. But the way highflow talks it's hard for them to keep em in stock currently.

hehe, just got one to play with!

[Pedalmonkey]

Block looks about as close to Mcoffeys direct Die cooling as you could get. Looks like it would need a powerful pump too. lets see some testing!!!!

[headala]

Cool, we look forward to seeing your results! Could you post a few internal pics? The ones at the beginning of this thread are too small to see the flow route.

Internal Pictures

[skinnee]

Good pics Marcus!

Did you have any difficulty getting that o-ring back in? I struggled with that thing for a good 20 minutes after disassembling the block for pictures.

[anzial]

highly restrictive, me thinks.

[HESmelaugh]

Great pics, marcus!

[headala]

Highly parallel design, just like IBM's internal design. But I worry it would be prone to jets clogging.

[skinnee]

according to my calipers base plate is just shy of 2mm. the block construction is interesting/different from what I have seen from other companies. I would be surprised to see the plate warp with the stock mounting hardware. There is a slight center aligned bow to the base.

Thanks Skinnee,

I agree, very cool design. Can't wait to get my hands on one.

I completely misspoke, baseplate is just over 1mm thickness. I will change my original post. I knew I should have waited till I got home and checked my notes.

[Vapor]

Do want

No VAT for USA buyers, right?

[headala]

Gosh I wish there was more info about this block.

[saxile]

No VAT Vapor, I should know, I bought mine and Skinnee's lol, I love it and find it no more restrictive than the d-tek v1 with the quad split nozzle, course I'm not measuring flowrate with tools just how it passes through my res.

[ILikeCosmosS]

this block is really different i dont think it might succeed it migh just restrict flow

[saxile]

not really, a single 355 with xspc res top can handle the phobya, xspc 4870 razor f/c block, and blackops nb block with ease

[skinnee]

If you guys are ok with not seeing thermals yet, just pressure drop...I can post that info.

Ummmm....let's wait...

[skinnee]

alright, hotdun. You have now volunteered yourself to run distraction while I prep for thermals and test!

I made a review (in Dutch) of this block you can find here. Compared it to a XSPC Delta and the Supreme. Supreme was the best block in my tests (my fist one btw), not by much though.

Here is the overall 5 mount graph from that test:



avarage temps over 5 mounts:



And here the best mounts:




tempprobes used for water and air I used are the Dallas One Wire DS18B20 (two for water and two for air; next time it will be 12 for air) connected to a Crystalfontzpanel with SCAB. Each mount was a 30min log time and 50min warming up.

[faster3200]

Coolfris, what caused the huge difference between the mounts on the Phobya? Is the mounting system not very good or did you just get one bad mount?

[Hondacity]

coolfris

thanks for the review...i'm now convinced about...xspc delta v3

and the ek supreme..reigns supreme..i guess the bowed surface helped alot...

and the phobya..it just scares me..lol thin base...tsk tsk..i don't want it...

[coolfris]

Third mount of the Phobya must be indeed a bad mount. The look of the imprint on the IHS was not very different from the others though. Maybe next time I should do more mounts and pick the best 5 within some given range, or something like that. I worked on the data after all the testwork. So maybe next time I will work on the data during testing the blocks. For a better temp resolution I will double logging time so there will be also more time for working during testing.


One thing I also noticed that the Phobya is a bit of a noisy block. Maybe it was because of the 2 DCC's in serie I used.
