Martin you have to test new Supreme HF to make it correct on your website, cuz it looks like even EKWB's cheapest version outperformance Koolance flagship (and it costs less then 1/2 price of Koolance block).
You have to keep the production values of the 370 in mind.
That is why it costs so much more.
The Nickle Plating is far more sophisticated than EK´s.
Also it is "supposed" to be scratch proof^^

The pressure drop of 1.2PSI at 1 GPM means that the 370 has better flowrates than the EK at least according to the tests of Martinm.

I am not sure what pump he used though so don´t quote me on it

I have just sold my MM Extended Ascension and therefor also my 1080 rad because I am getting a LittleDevil White.
Therefor I got a 480 Phobya G Changer 1.2 instead and my test results wit hthe Koolance 370 should be more accurate.
It is still in a single loop but it should be less flucuated by the 480 cooling ability compared to the 1080.

Here my CPU:


Koolance 370
D5 at setting 5
CPU Single Loop with 480 G Changer 1.2 and Gentle Typhoons at 700RPM
Idle with opened window:16 C
Idle with closed window:18 C
Load with opened window:44-46 C
Load with closed windows:47-49 C
Ambient:15-17C

i7 950 4.09 ~ 4.1 GHZ at 1.21 Vcore
CPU wattage at Idle:94 W
CPU Wattage at Load:130W
But you can see that in the screen

Looking at the important info....

What is your rooms ambient temp? If its 62f as you state, you need a more realistic room temp 70-75f (21-24c) where the majority of people run their systems. Is your loop cpu only? Is your oc at that voltage 24/7 prime stable?

These are all things you need to take into consideration when comparing test results.

By theory you shouldn´t be able to get lower temps than the ambient.
But I pretty much also get those temps at higher ambient tempretures.
Clocks are perfectly stable but it is not a golden chip just the structural enhancement of the GA EXUD5 for more efficient overclock.

At midday with an Ambient of approximately 20-24 degrees temps rise correspondingly at a rate of 2-3 C.

I think this is possible due to the minimal TDP of my CPU.
The 1.21 Vcore only requires a very little amount of Watts to be dissipated I think that somehow stands in relation to the marginally lower CPU temps compared to the ambient temps.

Yes it is a CPU single loop.
When the 2x6950 CF EK Blocks are included I will add a second 480 rad.

I find it hard to believe that your idle temps are almost even to your ambient with a 480 rad and the fans only moving 700 rpm. What are you measuring your temps with. Cause I can guarantee you your chip inst as cool as your ambient temps unless you are chilling.

The Phobya G Changer 1.2 is a Low RPM optimized rad.
Also the fan speed is controlled by my Heatmaster.

I only measure the absolute temps of the cpu not Delta T that is probably why it is a little off.
But the Koolance 370 is still an extreme performer and the incredible production values +superior mounting + better looks make it the better block in my oppinion and that is worth the extra $.

Considering the nickle flaking incidients of EK I will never touch an EK Nickel product ever again.
They just use poor quality for most of their products
