Overview

Hardware:
 
Manufacturer:
 
Price at time of Review: $69.99 on newegg.com
 

WHAT WE LIKED:

Dual Reservoir, excellent cooling solution, easy installation, built-in temperature indicator, low block clearance
 

WHAT WE DISLIKED:

Bulky fan with pump
 
BOTTOM LINE:
Although the radiator/fan might be bulky with it's newly integrated pump, the performance is well worth the new configuration. It is easily mounted with universal hardware, and the Kuhler H20 650 should be on your short list if you are looking for an affordable AIO cooler.

Performance

Our test setup is as follows:

Gigabyte GA-990FXA-UD7

CPU: AMD FX-6300

GPU: Gigabyte R9 280x Windforce

RAM: G.Skill Ripjaws 16GB (2×8)

PSU: Raidmax RX-1000AE

DRIVES: 320GB Western Digital 2.5″ , 2TB Western Digital 3.5″

Cpu Cooler: Antec Kuhler H20 650

Case: NZXT Phantom 630

Testing methodology:

All tests are run using Tuniq TX-4 thermal compound for comparison purposes. The CPU and heatsink was cleaned with rubbing alcohol and Tuniq TX-4 was reapplied. Tests are run at stock (3.5GHz [with 4.1GHz Turbo Boost]) and an OC at 4.8GHz (no Turbo Boost). The system is left to idle for 20 minutes and a baseline temperature is recorded using HWmonitor and confirmed by OCCT sensors. An OCCT test using Large Data Set was ran for 20 minutes and the temps are recorded again. The recorded temperature is the average of the 6 cores. Since ambient temperatures can affect CPU temperature readings ambient temps are recorded during idle and full load testing. The ambient temperature is then subtracted from the recorded CPU temperatures resulting in a Delta T measurement, (or how many degrees above ambient the CPU cooler keeps the CPU). This levels the field for different ambient temperature tests.

As stated, the Kuhler H20 650 was tested running stock settings and then overclocked to 4.8GHz, I ran the same tests compared to the AMD FX-6300 stock cooler, ThermalTake 2.0 Pro and a custom loop.

As we can see, the Antec 650 had a huge 14 degree drop from the ThermalTake 2.0 with only a difference of 6 degrees under load compared with a custom loop. Next, we’ll see how it handles under the stress of an overclock.

Under a 4.8GHz overclock the Kuhler H20 650 really showed its true colors, beating the previous leader by a full 14ºC and was only 11ºC behind the custom loop on full load, I was quite surprised at how well this performed and wasn’t expecting this much of a temp difference. Granted this isn’t the most powerful loop out there but it did perform exceptionally well.

The LED on the block was an added bonus; the temperature changes as the temperature becomes hotter. From cool to hot, the colors cycle through from a light to dark blue and then change from a light to dark tint purplish.

    Well got this cooler yesterday….

    quite impressed with the performance.

    Temperature levels are down by miles.

    all i can say at rs4700/- its a steal.

    all big players are selling this at way higher pricing than an indian web store martnext.com, they offered me Cash on delivery that took 3 days and i was quite impressed by them hats off, you got a regular customer
