Flowrates of Koolance 350 / EK Supreme / DTek FusionV2

[Hondacity]

Test Configuration

Pump1: Swiftech 355 with XSPC reservoir top
Pump2: Swiftech 355 with XSPC Acryllic top
Radiator1: HWLabs 480GTX
Radiator2: Thermochill PA120.3




other stuff


Some notes:
- test was done purely for flow
- when I ran single pump, pump heat was greater compared to having two pumps in series. ( less stress on pumps in series?)
- water temp got warm when i had the rad fans off...18w is alot, goods fans and rad is a must. my overclocked q9550 eats around 95w(stock)+90w(additional watts consumed when oc'd)
- i still(or might) have to replace the pump with the swiftech 655 + EK X-top
- i still(or might) have to interchange rads mcr320 and/or pa120.3
- waterblock testing on I7 will come too(when newegg ships my stuff)

Thanks! Interesting results. I didn't know the Koolance block was more restrictive than the Supreme.

[lyl]

Test results are always appreciated Might I ask how flow was measured?


For those not familiar w/ the Koolance 350

[Polizei]

Wow... that is uber restrictive.

[Hondacity]

i used a flow meter

[Utnorris]

Any chance to redo the test with a different rad like the Thermochill or Feser to see if it is the rad causing some of the restriction?

Actually, it'd be better to remove the rad altogether to see actual flow rates of each block.

True, but how much does that matter when no one runs a loop without a radiator?

[T_Flight]

whew, man that block really slams on the brakes. It's less than half the flow with the same rad and pump compared to the DTek.

.8gpm is kinda low. Dual pumps with that setup looks like a smart move...or the uber Iwaki.

[Waterlogged]

Also very true....but, these results are for only 6 out of a myriad of possible combos. For better results testing should be stripped down to basic elements so the variables that could possibly skew results are limited.

I'm not saying this testing is worthless (it's actually pretty decent), I'm saying it only gives results for some specific layouts, which doesn't help everybody.

[Hondacity]

RD30 is coming too, I'll switch the radiator to a Thermochill tonight (Utnoriss' request)

I'm probably stupid, but what do you mean here? And how was this measured?

[warriorpoet]

This is probably a really dumb question, but isn't the midplate installed 45 degrees off here?

[The-Fox]

Wow, that is some restrictive block !!
I think we got a new block entitled as a flow lover

Thanks for the test results Hondacity

Looks like it to me but IDK.

I think it can only go on one way. You see the little hole in the upper right corner and the little pin that aligns it.

Came to the same conclusion and told dean this a while ago.
However it should be the other way around im guessing. (more restriction does not mean more work on the pump impeller.)

Didnt honestly think the KL-350 would be more restrictive then the supreme.

[Hondacity]

i just added the pa120.3

enjoy

[NaeKuh]

Yeah very nice honda.. thanks for your flow testing..

Really suprised me how restrictive it is.

NOTE:
Blah sorry to derail this thread, but seeing how a lot of noobs will read this and still not know what cpu block to get.

How many people would want me to write out a nice short note on how to pick out the proper cpu block?
You guys are ignoring classes in blocks when picking, and were back in the 2006 when everyone got a Storm without knowing what it was and got worse temps then a apogeeGT.

I would really like to see that. I think I have a decent handle on the current blocks but, I still consider myself a noob and I think this would benefit many people here including myself.

You need to match the block to the loop. CPU only loop it's ok for the block to be restrictive. Multi-block loop such as chipset, GPU and CPU you should get a low restriction block. IMO of course.

[Hondacity]

these only show flowrates...

i will test them on the i7 when it arrives, hopefully dtek will have the mounting bracket for the fusionv2...

at the moment i have this q9550...and been waiting for a good time thermal testing these three

and i'm contemplating on cpu+gpu results, i haven't seen real data on how flow rates affect the dtek gfx waterblock..

actually no.

theres a dot whick you allign the base plate with the mid plate.

[Waterlogged]

I think a lot of ppl are missing the recessed channel at the end of the grooves that the water dumps into to be whisked to the block outlet.

I know I missed it until you pointed that out.
