Best CPU Block - EK Supreme HF vs Swiftech Apogee XT

[Lafas1987]

Hello to all!
I am thinking to change my old cpu waterblock.
My current Water Circuit is:
CPU Block: Eleven
Pump: Swiftech mcp655
Radiator: airplex 360 XT
Reservoir: A big one! I dont remember model!


I am between:

EK Water Blocks EK-Supreme HF
http://www.aquatuning.de/product_inf...939-XEON-.html

Swiftech Apogee XT Extreme
http://www.aquatuning.de/product_inf...-1156-1oe.html

1) Which is the best block?
2) If i change my current block with one of the aboves, will i see better temperatures?

Thanks for your time.

I like them both, each design has things going for it. Temps should be about the same.

I'd think you'd see better temps, just don't get your expectations too high.

[lowfat]

The Supreme HF edges ever so slightly ahead of the XT. The XT is quite a bit more restrictive. Saying this, I think the mounting of the Swiftech is leaps and bounds better than the Supreme HF.

Ever consider this?

So, i have to decide according to the price or the visual appearence.
My expectations are not too high i think. I want to have about 5-6C down.
Is this too high?
If i did that, i will lap my cpu for 3-4C down.

Do you say, that the Swiftech fits better than Supreme HF?

The Price is very good. But i want the best CPU Waterblock for phsycological reasons.

Finally i have to say that i use the following tubes:

Do they fit the following Compresion fittings?

...And something about cpu block installation:
Is better to install the block horizontally or vertically?

Lately it's hard to choose "best CPU Waterblock".
They each win in different categories.
- imho best price/performance wise is XSPC Rasa
- absolute best temps wise (with only very small win in tenhs of degree though) is Aquacomputer Kryo XT with thick O-ring
- imho best looks wise is Koolance CPU-360 with still respectable performance and good mounting sys
- imho best overall for me is EK Supreme HF with 2nd best cooling performance but it manages to gain that with much less restriction to flow making it good choice for all-in-one single loop LC setups
Most top cpu waterblocks these days perform very close. To each his own i guess. You have to define, what's "BEST" and most important for YOU, and only then others can suggest/advise best block basing on that.

[systemviper]

I like the both, i like the look of the XT a little better but
am leaning more towards the High Flow

[dengyong]

I'd go with the Swiftech Apogee XT for it's mounting system.

[Lafas1987]

I see...
Now a third block in the game! Oh My God!
I will choose by luck.

Ok, lets see...

From what i have understood these CPU Waterblocks need high pump preassure, right? Ok, i have it!!!
From the other hand my current cpu block works with low pump preassure and high pump preassure the same. Imo this happens because is very simple inside.
Am i wrong until now?

I will choose the cpu block for its easy and good installation and of course for the lowest temperatures.

For AquaComputer cuplex kryos XT the reviewer said:

Despite the mounting system, I'm really digging this block for its performance and its looks.
http://www.xtremesystems.org/forums/...d.php?t=254728

EK-Supreme HF (#1) is a little bit better than swiftech.
Swiftech has better mounting systems as it seems.

I am near to buy EK-Supreme...
I think that has good mounting system and easy installation. Is has the same installation as my current CPU block.

The one with Acetal and the other with Acetal+Nickel.
Which on is the best?

The fittings that i will choose, will be the followings:

We have tested and retested and tested again the suprme vs the xt in our laba and were never able to beat the xt perf wise. Flow in supreme is indeed less restrctive. - I also clearly demonstrated the actual influence of flow in a recent white paper.
If you want to make your choice perf wise I clearly maintain that xt is no1.

[PatRaceTin]

someone may prefer "Good looking" than "Good performance" haha

[Johnny87au]

I prefer the HF anyday seeming as i use alot of blocks and the low restriction actually helps quite a bit.. Anyhow heres some charts for comparison...

[Oberon]

I'm glad my HK 3.0 is still holding up well

gabe: out of curiosity, what was different in your tests? I'm guessing - heat dump because of different (lesser/bigger?) overclock and overvoltage? Different TIM used? BTW, have you tested different XT blocks for fluctuating performance? - I wonder if it's not possible that pin machining might slightly vary for different pieces of waterblocks, and it's possible that you're testing slightly better exemplar, while skinneelab might have recieved slightly worse (or slightly better HF exemplar). Also you double checked to use most restrictive p#1 with HF? Apart from that i'm out of ideas why results might differ except maybe you testing in only below 0.9gpm, where XT outperforms HF.

Sorry im not sure what you mean, Plate #1 delivered the best temps thats why he used it, comes default with all the Supremes now i believe..

[Church]

Johnny87au: It didn't at first. And i hadn't notice him ever claiming that he used it, so it never hurts to ask. Of course you might be swiftech employee and be familiar how exactly tests were performed? I simply listed what imho might differ between his testbed and skinneelab's that might affect test results/arrangement.

[Lafas1987]

Will i have the problem at 3:22 with XT or HF?

I believe those are skinee's test results

2 to 3 tenths for the best mount.

[penguins]

johhny, he (churchy) wasn't referring to skinnee's test results he was referring to gabe's reference to his own testing.

and as i recall they are shipped with plate 2 according to what i've heard on here ( obviously scientific lol )

I'm also curious if you used the Plate #1 gabe.

when it all comes down to it. which mounting hardware do you like the best, and which looks the coolest!!

[Martinm210]

Go for the xt...that mounting system is worth more than fractions of a degree for your typical user who does not mount blocks all the time.

The mounting system on the supreme is still the old bag full of washers and nuts ready to fall under your motherboard and no limiter on how much mounting force and also allow mounting the block with uneven pressure.

The xt system keeps everything together...so nothing to loose and mounting pressure is perfect and even on all four corners.

a bad mount can result in several degrees loss..so I think the better mounting system is more important for folks that only mount a block once when doing upgrades.

my 2c

[Lafas1987]

XT is big block. My Mobo has passive coolling on mosfets and I am afraid that XT not fits.
Do you think that this is not a problem?

About compression fittings now:
As Johnny87au said, i will not have problem with compression fittings as i told above.

Ok, i will go for XT.
More fancy and better mounting.
The bad thing is XT can not mount on sandy bridge...

Agreed, the mounting system on the Swiftech blocks are far superior. Novice block mounters will reap more benefits from it. I have an HF on my 920 and it is a great block but I use more care in getting each bolt to equal tension. The GTZ on my 9770 does a great job and it was soooo easy to mount. Can't go wrong with either block and it comes down to personal preference and build experience.. YMMV

Well supreme HF then

[Lafas1987]

I searched about fittings.
The result is:

XT:
If you wanna fit compression fittings, u have to rotate Inlet to 90o degrees for more space bettween them.
http://www.swiftnets.com/products/apogee-xt.asp
1) If i do that, i will have lower flow or something?
2) Is it easy?

HF:
I am not sure if HF has space for Compression fittings.
Maybe yes, maybe no.
I found the following:
http://www.feser-one.com/site/produc...roducts_id=286
http://www.ekwaterblocks.com/shop/EK...0046990181.pdf
So i will buy (if i finally buy the hf) Compression fittings 45o Angle,
http://www.aquatuning.de/product_inf...ck-nickel.html .
Someone with HF can tell as if i am wrong.
