Review: testing antec khüler h2o 620 with i7 3930k and i7 3770k

Almost a year after analyzing the first review of the Antec 620 I have tested the performance of the second review with an Intel i7 3930k 6-core platform 2011 and the recent i7 3770k ideal for Z77 boards.

Warranty	3 years

The box is the same as the one we had from the previous Antec 620. The only difference is the support with the 2011 socket.

Includes a fantastic instruction manual in Spanish.

Holders for 775/1555 or 1556/1366 sockets.

Screws for installation in socket 2011 and fan anchor screws on the radiator and fan.

And for the green guys at AMD you also have AM2 / AM3 anchors.

120mm fan that runs up to 1700 RPM.

This liquid cooling kit has a very good aesthetic.

Radiator 120 mm and 3 cm thick.

Corrugated tubes that give an elegant aesthetic and great flexibility for installation.

CPU block with pump included.

Top quality thermal paste. Considered by experts to be the best on the market.

I have installed it in socket 1155 with an Asrock Z77-E Itx board. Being a special format I have had to play a bit with the holes. Then I tested it with an Asus Maximus IV Extreme.

And its new aesthetic is incredible. Let's see the before and after:

For my taste, the new installation and hardware support is infinitely better.

Once mounted inside the equipment.

TESTING BENCH
Processor:	Intel 3770k / Intel i7 3930K
Base plate:	Asrock Z77-e ITX and Asus Rampage IV Extreme
Memory:	Kingston Hyperx PNP 2x4GB
Heatsink	Corsair H60
HDD	Kingston Hyperx 120gb
Graphic card	ASUS GTX580 DCII
Power supply	Thermaltake TouchPower 1350W

To test the actual performance of the heatsink we are going to stress both the Intel i7 3770k CPU (Socket 1155) and Intel i7 3930K (Socket 2011) with prime numbers (Prime95 custom) and two 12cm Phobya fans. Prime95, is a well-known software in the overclocking sector and allows us to detect faults when the processor works 100% for long hours. Why won't we use Linx? Socket 2011 is not currently optimized, and I would make the effort.

How are we going to measure the processor temperature?

We will use the internal sensors of the processor. For this test on Intel processors we will use the “Core Temp” application in its version: 0.99.8. It is not the most reliable test, but it will be our reference in all our analyzes. The test bench will be around 28ºC ambient temperature.

Let's see the results obtained:

Now that the Antec Khüler 620 is compatible with the 2011 socket, it is positioned in the best quality / price option on the market in Liquid Cooled Kit with single radiator and wrinkled tubes.

In our test bench we have carried out hard tests with Prime95 Custom (24 hours non-stop) with the two best microphones on the market: i7 3930k from the 2011 platform and i7 3770k from the 1155 platform with Z77 chipset.

WE RECOMMEND YOULumia 950 and 950XL discounted before launch

As we can see in the table the results are excellent and its performance is somewhat higher than that of a normal heatsink.

Another of the improvements that I have to highlight is its new installation system more with an easier installation system and a more elegant aesthetics.

In short, Antec is doing a great job again with its liquid cooling kits and the results obtained with the Ivy Bridge and Sandy Bridge-Extreme platforms are outstanding. Great job Antec!
