Review: antec h20 khüler 920

In August we analyzed the Antec H20 Khüler 620 liquid cooling kit. Today we bring you his older brother; the Antec H20 Khüler 920. With double fan, a thicker radiator and the new Antec profile management software.

Antec Khüler H20 920 is the second Liquid Cooling Kit equipped with “Liquid Temperature Fan Control” technology that controls the pump and fans automatically, without the need for controllers. In this way, the fans run at higher revolutions if the liquid heats up. Furthermore, Antec provides us with management software to personalize our own profiles.

We are already used to the Antec packaging design. Cover with illustration of the kit and the back all the features of the kit.

The packaging is very good. Foam sheet and impact resistant cardboard.

The kit includes:

• Antec Khüler 920.2 Liquid Cooling Antec 2400 RPM Fans. AMD and Intel Installation Kits. Drivers and Manuals.

Quick guide and software installation cd.

The fans are two Antec from 700 up to 2400 RPM. The cable is meshed and we like its aesthetics.

The flexibility of the tube is impressive.

The kit provides us with a simple radiator with an excellent finish.

The cpu block has slightly changed its aesthetics. Now it incorporates a blue led the logo.

The radiator is 5 cm thick. This width will help us dissipate much better than the 620.

The base is copper and has pre-applied thermal paste. Its texture reminds us of Antec Formula 7.

We have installed the RL in socket 1555. The first thing to do is install the back:

Support for Intel socket, we install the blue connectors:

It is time to fit the liquid cooling block; we turn clockwise and the block goes in. We tighten the screws and the result should be this:

One of the small features of this kit is its management via software. Once the program is run, it allows us three profiles:

• Extreme: Maximum power: 53-55db (One locomotive). Silent: 10-20db (pretty quiet). Custom: We can customize at our whim the speed of our fans (recommended) and increase / decrease their flow.

In addition to the "Dashboard" option. We have Graph (Option), Option (reading options) and Fan Control:

This section allows us to adjust the maximum temperature of the liquid. We can also manage notifications of temperature and fan rotation speed.

NOTE:

It is possible that the software does not recognize the Antec 920 and if you google you find that your unit is defective. We solve it: inserting the cd -> start -> right button to "Computer" -> manage -> device manager -> right button to the Antec icon -> Update software -> search for software from the computer on the computer -> browse -> select your CD and next. The driver will be installed automatically and will be recognized.

TEST BENCH:
Box:	Dimastech Easy v2.5
Source feed:	Seasonic X-750
Base lacquer	Gigabyte GA-Z68X-UD5 B3
Processor:	Intel i7 2600k @ 4.8ghz ~ 1.34-1.36v
Graphic card:	Gigabyte GTX 560 Ti SOC
RAM:	Kingston Pnp 2x4GB (8GB) Cl9
HDD:	Kingston SSDNow + 96GB

To test the actual performance of the liquid cooling kit we are going to stress the CPU with full memory (Linx) and prime number (Prime95) floating point calculation programs. Both programs are well known in the overclocking sector and serve to detect failures when the processor works 100% for long hours.

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 29º ambient temperature.

In our test bench we will use the following 12v fans:

• 2 x Antec 2400 RPM at 12v

• 2 x Scythe Nidec 1850 RPM at 12v

WE RECOMMEND YOU Galvanic Corrosion in liquid cooling What is it?

Antec has surprised us with its Khüler liquid cooling kits. During the analysis we have seen that the Antec Khüler 920 has excellent performance, thanks to its 5 cm thick radiator and its two 2400 RPM performance fans.

In our test bench we have made a versus against its direct rival: Corsair H80. We have used our Intel 2600k with an overclock of 4800 mhz and 1.36v. As we have previously commented its performance is extremely good, for example we have obtained with prime95 at FULL 63ºC !!!. You must remember that we have always recommended that the maximum temperature for a good overclock with Sandy Bridge is 80ºC. With this kit we are very far from reaching that limit.

We also liked their profile management program. By default we have three:

• Silent: Low revs.

• Extreme: 2400 RPM (PWM).

• Custom: We can create our own profile.

We do not see it necessary to change the fans that come as standard Antec. Performance is slightly higher than the famous 1850 RPM Scythe Gentle Typooh AP15. If you choose this option, the Antec program will not let you create profiles with 3-pin fans. EYE: only with PWM fans (4 pins).

In short, if you want to get the most out of your processor with the best temperature, the Antec H20 Khüler 920 is the best compact Liquid Refrigeration Kit on the market. It sets its kit management and monitoring program apart from the rest. At all times we will know both the speeds of our fans (without the need for rehobus) and the temperature of the liquid.
