Swiftech Apogee GTZ vs D-Tek Fuzion V2 As-Shipped

[alacheesu]

That curve? It's very close to be linear actually
Btw, martin used DDC3.2+XSPC top in the GTZ-FuZion testing, didn't he? the flow rate decline with a D5 should be even bigger.

Wow, you're right, I was wrong. It is almost linear.

However, I'm still sure you cannot do the calculation the way you did. If you fire up up Martin's estimater, plug in the Fuzion v2 and MCP 655 you will have a flow rate of 2.01 GPM. Fuzion -> Supreme yields 1.22 GPM or 0.79 GPM less.

Adding a D-Tek GFX to the loop and doing the same yields a difference of only 0.34 GPM. (1.34 GPM to 1.00 GPM)

If you take into account that pressure drop in the blocks is a function of flow rate, the results make sense even if the pumps PQ-curve is linear. But I guess I could be wrong again.

Anyway, if you added enough blocks to get the flowrate to less than 0.4 GPM and then replaced a GTZ with a Fuzion you would, by your example, have negative flowrate, which obviously makes no sense.

And by popular demand, yes 3/4" compression fitting do fit, you just need to slip an extra o-ring over the threads to raise it a little.

Does this also occours with the Koolance G 1/4" Compression Noozles ID 3/8 ?

Does the GTZ need to be lapped to help temps with C2Ds?

I don't know, I don't have any Koolance fittings yet, but I'm trying to get a few so I can check compatibility with all the types of popular fittings on all the blocks. It's really not a problem to use the extra o-ring, you can take one from the original shipped barbs. There is a very deep recess there that holds it in place nicely. Generally if the 3/4" OD type compressions fit, you should be able to fit just about any fitting. The extra o-ring is just needed to fill in that recessed slot.

No, I wouldn't, it comes in very good condition as is. You especially wouldn't want to lap it while assembled, it has a significant bow that you could make worse by lapping.

Generally I don't lap waterblocks anymore unless you somehow scratched the base badly. I do lap the processor IHS though, that can be helpful especially if you IHS is slightly concaved. That does void your warranty though.

If a base gets a little oxidation from fingerprints etc. I just use paper towel and your favorite thermal compound as a polish. It works pretty well and helps embed good TIM material into the pores of the base.

I already have my CPU lapped and temps are a bit high. Trying to troubleshoot my temp problem. Thanks for your response.

Start a new thread about your problem and note some details, and if you have them, some photos of the setup.

There are lots of very talented folks on the forums that have gone through that one time or another. If you post the details in a new thread, alot of those folks will try to help out..

If you can spell out the following that will help out alot:
Processor, Speed, Vcore
Radiator, fans, location of setup
TIM material used, application method.
Any other blocks in the loop and details about what they are cooling.
Pump, and any tubing details...etc.

Great work as usual Martin.

I don't know, I don't have any Koolance fittings yet, but I'm trying to get a few so I can check compatibility with all the types of popular fittings on all the blocks.

I love the way every second post that I see by you contains something along the lines of "I'm going to test _____ as soon as I can.". Keep up the great work.

Nice review Martin!!!
Dtek Fusion v2 is good!

[Boogerlad]

Thanks Martin! I love your work. The graphs are so clean. Now i understand how much work you have to go through making all these charts. It's so detailed.

[systemviper]

picked up the GTZ and the EK 790i blocks, I am excited to get them rocking, thanks for the info on the Apogee GTZ.

[louie101086]

martin you left one thing unanswered which performs better on a dual core? my 2 cents: i think the fuzion would do better because the input barb is directly over the core

[MaadDaawg]

I had been thinking about replacing my GTZ with a DD TDX on my i7 rig. Now I'm thinking I might just leave it alone

That would definitely be a downgrade if I ever saw one...

[Ol'Baditude]

That's quite a statement, have you tried both of these blocks yourself?

But MadDawg, there is absolutely no reason to switch from what you have. In my experience the MC-TDX, while an excellent block, will not net you any advantage over the GTZ.
