Heatkiller Rev3.0 internals at Cooling Masters

[D-Cyph3r]

I still cant see how this can have such a huge advantage over the Supreme, which in every other test i've seen is literally within margin error of the likes of the GTZ, Fuzion V2 and Delta V3. :S

[Fr3ak]

The same Enzotech as in Martins review?

Yes the same Enzotech, but I used a different measuring method. At 1:56 hours of computing time that my test setup reaches after 30 mins. There is a temp peak at this point for about 2 minutes. Temps usually stay at peak during this period and I note down those temps instead of measuring a long time intervall that Martin uses. His method might be better and more accurate. I will do more tests using different methods to see what turns out to be more accurate in the end.

I only used a Black Ice Xtreme 240, so my deltas are way bigger than Martins. Between my best and worst block are almost 15C. The measurement margin lies within 0.5C, usually the results after several mounts only vary by 0.2C.

But as I said, I only tested 5 blocks in the latest review and had to use new tubing, so older test results might not be accurate. I did all tests with a D-Tek Fuzion V2 again which was slightly better than a EK Supreme in my previous tests. I am actually thinking about publishing my articles of the print magazine in some way or the other, but converting them is not an easy task.

So you publish your articles in a real magazine? What's it's name and where can I buy it?

[Baleful]

That block looks to be a real contender. I can't wait to see some final numbers.

The magazine is called PC Games Hardware/Extreme, but I don't think you can buy the magazine outside of German speaking countries, which are Germany, Austria, Switzerland, Luxembourg, Netherlands and Belgium.

[Hondacity]

interesting results...how many mounts did you use? the sapphire better? have you tested it already?

I want ONE copy!!

You have a 40C+ delta?!?!

So we're talking like idle at 25-30C and load at 70C?

I think for your testing you need to have a bigger/better radiator so you can take that part of the loop out of the equation.

[Fr3ak]

I already said that in my earlier post. I use 3-5 mountings. In case the results vary more than 0.2C after 3 mounts, I mount them 2 more times or more, depending on the variation of the results.

Buy one then

Read my post again. I am talking about a delta between water and core temperature, not idle to load. I originally used a dual radiator to have a common rad for a CPU only loop. For Nehalem, I will change the test equipment.

I'll must take boing to going in germany!

it seems a nice wb...

no review yet?

Fr3ak, can you say if there's enough space to fit Bitspower 1/2" fittings on this block?

[Eddy_EK]

Fr3ak, can you say if there's enough space to fit Bitspower 1/2" fittings on this block?

I am sure, there is NOT enough space.

[p2501]

I am sure, there is NOT enough space.

Okay, now that's a let-down.

Edit: Well the guys at Watercool said it'll fit barbs up to 20mm overall OD, could anyone with Bitspower 1/2" barbs measure the absolute max OD for me?

[Fr3ak]

The distance from G1/4 hole to hole is 21 mm.

As for presentation of results: I am working for a print magazine and I hope you can understand that I cannot copy and paste the whole article. Otherwise nobody would buy the magazine with the result of losing my job sooner or later.

I pretty much gave you all information needed in the first post I made. To measure air and water temperature, I am using a standard temp probe that is connected to a Aqua Computer Aquaero and a external meter. I measured water temp in the reservoir.

Anyway, especially watercooling tests can vary a lot due to different test systems or mythology, so I can only advice you to read as many reviews as possible and form a conclusion for yourself.

Personally, I don't really care about every C in my 24/7 builds as long as they are powerful and very silent at the same time.

[Baleful]

Maybe not enough space stock, but with the proper bitspower 45's you should have no problem.

Cooling performance wise, the Heaetkiller 3.0 is the second best water block I ever tested. Due to new tubing for my test equipment, flowrate cannot be compared to old tests, but temperature seems to be within 0.2C with the little higher flowrate, I retested 2 blocks and the measures temps were within 0.2C, but other blocks might behave differently with a change in flowrate, so don't blame me for the results posted below.

Temperature delta:

HK 3.0:
38.8 C (Eheim 1046)
37.2 C (Laing DDC-1T)

EK Supreme:
42.8 C (Eheim 1046)
42.7 C (Laing DDC-1T)

Testing mythology:

Asus Maximus Formula, QX6700 @ 3.46 GHz, 1.5 V, 30 minutes Prime 95, 3-5 mounts depending on variation, listed values are the difference of the average water and the average CPU temperature.

That s pretty good ^^ it would be nice to compare the HeatKiller 3.0 to the Koolance 350 (Ek supreme killer too, but very restrictive)

[headala]

Ok that was unexpected so on with the EK SUPREME V2 OWNAGE RRR FTW EDITION.

OMG I almost spit out my drink. I kindof miss him actually.

So does anyone this side of Atlantic sell HK stuff?

[scamps]

Just another kick in the shins:

I have replaced my D-Tek Fuzion V2 with the Watercool Heatkiller 3.0 LT


The flow is lower (of course I´d say), but the core-temps are better up to 3° on a Q9550 @3,84 GHz with several mounts of both ...
A real top product "Made in Germany"

Bundymania did a nice review with an E6400 @1,45 V and if (like I have supposed) the D-Tek is almost as good as the Supreme, his results do correspond with mine (Q9550 @1,3 V) and almost with the results of Fr3ak (details not known):

I have used a few of the HK 3,0 blocks for i7 builds so far (CU versions), and am pretty impressed with the results. Mounting system is also top-notch, just be sure to buy the matching backplate for lga 1366 (it's not included )
I don't have any EK Supremes with 1366 mounting though so I couldn't do any comparisons between them. I really like how you can easily optimize the HK 3,0 for single-die and multi-die CPUs by inserting or removing a separation plate into the block

...I really like how you can easily optimize the HK 3,0 for single-die and multi-die CPUs by inserting or removing a separation plate into the block

Curiously I had a (very) little bit better coretemps without this little plate - on a multi-die Q9550

Additonal information for users of bigger fittings: Watercool made a first revision of the HK 3.0 and increased the distance of the two connections from 20 to 21,5 mm (deliveries since last week).

[jcool]

Really? Mine performed about 2C better on a Q6600 with that plate installed. Maybe it depends on the block's orientation?

[redgabber]

I just bought a HK 3.0 CU and i m very fine with. Great waterblock, not too restrictive, can be used on multi-block single loop and DDC 3.2.

My temp are 41 to 47° in Prime95 Burn with 1.45v and QX9650

But i have a question about HK orientation.
I see the shower-jet is vertical. but why not rotate the block to 45° to get the shower horizontal...it would be better for Quad core ??

[wez3570]

I know this thread is a few months old but am I to understand for i7 the internal plate (inside the waterblock) should be removed?

Also, does anyone have a pic of the HK 3.0 with backplate..installed?

The long bolts don't appear long enough to reach the back-plate!

If I used the nuts (the ones that look like large silver stand-offs!) to secure the back-plate first then surely the mobo will still 'bow'
