I7 waterblocks Version2 (Ek Supreme LT | Koolance350 | Dtek Fuzionv2 | Swiftech GTz)

[ChaosAD]

Thanks for testing Handacity I would like to go with the 350 but given the price of 80 euros vs 35 euros for the EK LT i think my vote goes to EK and it will be my next cpu block

[Hondacity]

omg - for what are all those fans?

In which direction did you mount the 350 and the V2?

the fans? you're at xtremesystems

the v2 was tested horizontal..i doubt that rotating it will increase performance. but i will test that when i'm back also with the k350.

Nice job! Very informative. Looks like its time I upgrade from the V2. Does the orientation of the 350 matter as much as the LT?

probably not if you look at the internals..it looks like doesn't need special attention to it..but it will be tested

Thanks for the test

I'm still impressed by the Fuzion v2.. sure its last, but its FAR less restrictive.. in fact from that, the GTZ faired the worst because it beat the fuzion only slightly but it'll rob a lot more of your flow

i so agree here.. on core2 series my testing the dtek beats the gtz even martin had better temps with it..and better flow..

Ditto, I'm interested in a regular EK Supreme as well, so many people still swear by it

after several weeks...

thats why i wanted to test this quick..i know some would love to see results before their purchase...

Sorry, fans are for cooling down water and for nothing else on xs and elsewhere ...

I am actually testing the 350 on a Q9550 @4GHz. And I can´t believe what I see at the moment: This cooler seems to be most restrictive one I ever had*
What are your results in this?

* incl. Supreme, Cuplex XT di, D-Tek Fuzion V2, Heatkiller 3.0 LT

[Blkout]

Good information to know, but since I already own a D-Tek Fusion, I just can't justify spending another $50-80 for a CPU block for 4c difference. Looks like I'll just buy a 1366 mounting bracket for the Fusion.

increase heat load honda if your running dual pumps.

watch the heat load scale better on the KL-350. and i know your running dual pumps.

the block wont give you better temps at lower load, but it scales a lot better then the other blocks i tested with higher heat load.

this is why i kinda gave up after the third block testing i did personally.

[Hondacity]

higher heat load? i got a high heat load already... 250w approxiamately...

what was your heat load? if i increase the vcore higher...i get bsods

[NaeKuh]

higher heat load? i got a high heat load already... 250w approxiamately...

i was going as high as 1.55Vcore @ 4.25ghz and only noticed a 2C increase from 1.488

Wouldn't it be better to judge by the maximum temperature excluding bad mounts. I've always found that my max temp is on Core0. I'd call it a tie between the Koolance 350 and the EK Supreme LT.

[scamps]

I finished my test on a Q9550. Perhaps you should add the Watercool Heatkiller 3.0 to your review. If it is as much better on a i7 as it is better on a Q9550 ....

My little review could be find here (german language only):

it looks almost the same..if i remount the k350 several more times..i'd probably achieve lower temps...thats why i took the lowest temps..because its achievable..if you consider the max temps then realistically you're disregarding the better capability...

Great writeup Hondacity. Question for you on the GTZ, how was it mounted? Seems there is some debate on whether or not you should follow Swiftech's guidelines with lining the swiftech logo up with the release latch of the 1366 socket. I'm getting ready for my i7 build and wonder which was the best mount orientation for you?

[Envy]

high voltage i7:"This is MADNESS!"
high overclock".........THIS IS SUPREME LT!"

[warriorpoet]

Your fits top leaked!?!?!?!

[CedricFP]

So does the Supreme LT perform better than the Supreme? IF so, why is it cheaper?


Further, what are the mounting mechanisms of the KL 350 and LT? Is it a hard mount?

i followed the instructions..which gave better temps than not following instructions...

yes

Further, what are the mounting mechanisms of the KL 350 and LT? Is it a hard mount?

i'm not sure yet..but design wise its definitely cheaper...remember the xspc gpu full cover water blocks...

performance wise..i'd guess the LT will perform better...i have yet to mount the ek supreme

i used hard mount i get better mounting repeatability with my hard mounts

[Hondacity]

high voltage i7:"This is MADNESS!"
high overclock".........THIS IS SUPREME LT!"

what is that case? the rad mounting is beautiful...where is the harddrive? dang i need to beat your score...i only got 8.987

[NaeKuh]

This is the KL-350 done right owning on Linpack:





HT on Also.

Im gonna say this, for us xtreme people, i have yet to see a block out perform the KL-350. But you need the setup tho.

Wanna see a 920?

[SNiiPE_DoGG]

naekuh your only at 4.1ghz with a much lower voltage....

[Vapor]

Two different CPUs, can't really compare anyway

[Crazystang01]

Thanks for doing this write up I purchased a EK Supreme LT on blind faith before this review. Hopping it would preform

[NeedMoMegaHurtZ]

Thx for sharing the testing results! Very interesting...

[Petra]

Just because it's achievable doesn't mean that it's representative of the product in the larger scope and simply focusing on the best that you can achieve while throwing the normative data out does not make for good testing methodology.

Even with your data averaged, you're still suggesting that the difference between the 350 and the v2 is akin to the difference between one of Stew's Storm G5's and an MCW5000 (to pull a comparison from the past for the purpose of focusing on magnitude of design difference). Your spread doesn't seem at all odd to you, given the typical spread that controlled testing yields?

You have some reading to do and, since you don't seem to like hearing it from me, here's a good place to start (old but still plenty educational):

HT ON + Linpack vs superPI?

yeah i know,

:P

But i wanted to just throw it out.

Wow...Just got my 350 in today. I'm impressed to say the least on parts quailty and construction. I know one thing, you'll never have to worry about the hold down or backing plate flexing. That's for damn sure. I'm sure it's some where, but what's the proper orientation for a i7 920?

Can't wait to get this bad boy mounted. What a difference a year can make with a LC company, very well done.

andyc

Thank you

You can skim the optimization guide. Parts 3 and 4 mention correct orientation.

[shazza]

You guys sure have peaked my interest in the 350. Especially since my CPU is running in it's own loop with a PA 120.3. And ... Naekuh, that 965 looks fantastic. Is that just on water, or are you using something else as well? (sorry to derail the thread a bit, but this is good stuff).

While we could pick Hondacity's testing apart (e.g. run an analysis of variance on the individual data points, and you may find the statistical significance of the differences is less than you might think based on averages or the lowest number achieved) ... I really appreciate someone doing this. I cry every time I have to reseat my CPU block, so I appreciate the effort that goes into this.
