Waterblocks on i7 - Part 5

[masska]

i want a sapphire. (enzotech) It's performance is only 1. degree worse than the hk and is the most freeflowing of them all.

here you go,

Yes. M3x35 screw into backplate creating posts, then use thumb nuts and compress the GTZ springs by 6.35mm (.250") for 255N. You need a thumb nut with a wide flange, since our spring is 10.6mm in OD. I am preparing a kit. I had planned on sending you one.

Regarding methodology (lapped IHS or non-lapped IHS), it is evident that the vast majority of people do NOT lap their processor. A set of tests like yours, which is so incredibly comprehensive, automatically gains a massive audience. Because this audience is so broad, it would make sense that the tests be conducted to reflect the majority of use: non-lapped IHS.

HES??? Are we going to get your i7 roundup with an unlapped CPU??? lol

[santiagodraco]

Adding heat to the loop won't make a difference. Since it's delta temps we're looking at, you wouldn't find a significant change due to different water temperatures.
It's the added restriction of extra blocks that will make a difference. That's where the Temps in relations to flowrates graph can be a useful, albeit not perfect, reference.
Basically, for a restrictive loop, you want a block that isn't very flow-dependant while in a less restrictive loop the block's flow-dependancy is less important.

Though I also want to mention that the difference flowrates make and even the differences from one block to another usually aren't dramatic.


Thanks to everyone for the positive feedback, by the way.

Thanks for the explanation. I now realize that what you are saying is that you essentially simulated the addition of extra blocks by adding restriction. Nice to see thorough tests

I hope you are willing to apply the same sensibility to your own tests Gabe which suffer from a different yet similar flaw.

Indeed, be realistic about what represents the average users system on XS or otherwise, intimating that the average "extreme user" would use a pair of D5's on a cpu+gpu loop is a bit insulting. An "Xtreme user" would use 2 loops, most would run one pump per loop, most users water cool the cpu only...

[bluehaze]

So which block would be best for an i7 920 and GTX 295 single loop with ddc 3.25 pump and monsta rad? Still the HK 3.0? Is the HK 3.0 LT basically the same as HK 3.0?

[matsjuw]

Any update on the unlapped CPU? Or isn't that going to happen?

I haven't done any further testing yet. In whatever thread it was that the GTZ-on-lapped-CPU-problem came up, I asked about possibly adding spacers and retesting. Or maybe I asked per mail and someone else asked in the forums. Anyhow, Gabe said that this wouldn't make a difference so I didn't retest.
My rig is now set up for testing radiators and so for the time being, I can't do further CPU block tests. Once I gear it up for CPU block testing again, I might do a few runs on an unlapped CPU. I can't guarantee anything, though and I certainly won't retest all 20 blocks on an unlapped processor.

Yup, I'd still go with the HK 3.0. And yes, the LT version is the same. The LC version is the one with less cooling power, so to speak.

Think: LT = Light, LC = Low Cost.

[hellcamino]

I think the majority of tests agree on that point although gabe did say that he was releasing a modified mounting system for the gtz.

[skinnee]

I have the modified mount system and I have lapped and unlapped (soon to be lapped) chips to test with.

[HESmelaugh]

Good stuff.
I think I'm not going to bother then, since your testing will be as thorough as can be anyway, if I know you.

[skinnee]

Thanks HES!

I just wish Alphacool would have responded to my requests, would have been nice to include them in my testing. I will be releasing the results I ran on my lapped 965 soon and will roll right into testing all over again on an unlapped 920. I think I need to start buying TIM in 50 gallon drums instead of 30g tubes though.

[HESmelaugh]

Yeah I hear ya concerning the TIM. Don't TIM consultants sell their stuff in ridiculous quantites? I seem to recall tubs or barrels or something of TC grease. ^^

Also, I'll ask my Alphacool contact about this. Maybe USA isn't their target market yet or something. Maybe I can persuade them to send you a sample anyway. We'll see.

Heya folks well i need somes informations about Watercool HEATKILLER® CPU Rev3.0

Watercool got 2 models

Watercool HEATKILLER® CPU Rev3.0 775
and
Watercool HEATKILLER® CPU Rev3.0 1366

Question is ... is there difference between the models 775 & 1366 beside the retention brackets ?
does water blocks internals ares different or the same?

thx

[HESmelaugh]

The internals are identical, regardless of what brackets are used.

The 775 versions will have a tiny, removable plastic plate in the inlet barb. It's supposed to split the flow to hit the two separate dies on a Core2 CPU. The 1366 versions will have this plastic plate in the box, but not inserted. Either way, it can be removed or added.

[Capt Proton]

I would really like to get a HK LT. My problem is that I am still on 775. Not looking to upgrade for another year, but, don't relly want to have to change my waterblock at the same time.
It looks like you could use different mounting plates on the same block, but, I can find no evidence of them beibg sold separately from the actual block. I am aslo thinking that I could get one for 1366 and just drill holes in it for 775. That may not be the best thing to do either, as it looks like 1366 is on the way out as fast as it came in.
Ideas, suggestions?

[Vapor]

1366 mounting kit for when you need it

[Capt Proton]

Very cool. This tells me that no matter what socket is King of The Hill in 2010, I shall ne able to switch my waterblock over. Now, there really is no reason not to get the block, other than should I.

thx for the quick reply about Watercool HEATKILLER it help me alot

reason: Back Order Watercool HEATKILLER rev 3.0 1366
so if the 775 identical inside great new it fit on my BR

Thx

[BulldogPO]

Interesting review, would like to see wit nonlapped CPU.

[downforce]

Nice round up!!

Convinced me I need to upgrade my Apogee GT to a HK3 LC for my Q6600!

[PatRaceTin]

i will try HK3 LC or
EK Supreme LT Acrylic

[HESmelaugh]

Interesting review, would like to see wit nonlapped CPU.

Skinnee is working on that, AFAIK.
I'm not going to change CPUs for my tests. Can't cover all the bases...

I guess next time a new CPU for my test rig comes around, I'll do a survey on how many people want to see results on lapped or unlapped CPU.

[matsjuw]

This should get added to the Liquid Cooling sticky or martins/skinnees website as far as I'm concerned.
Awesome testing you did here HES.

[skinnee]

Skinnee is working on that, AFAIK.

edit: First results will be using a lapped chip. I am going back through and retesting almost everything and some new blocks on an unlapped 920.
