Zalman LQ320

The last system we’re going to cover in this roundup is Zalman LQ320. If you read the first part of this review, you may notice that the packaging is only different in the color of its bottom part.

Of course, the product name and specs you can see on the box are different, too.

  

Here is a photo of its contents:

The product is additionally protected with a soft 5mm cover from above. Like the other coolers, the Zalman LQ320 is manufactured in China. Its recommended price is $100.

Like the above-discussed Thermaltake, the Zalman LQ320 is based on the Asetek 570LC platform with minor differences. For example, there are decorative side panels on the radiator:

 

The radiator is exactly like Asetek’s original:

But the sticker reports a different wattage rating – 3.9 watts.

According to our measurements, the pump consumed only 2.23 watts or less than the Thermaltake’s. That’s why we don’t really know what exactly wattage the manufacturers specify on the radiator stickers.

The waterblock is thicker due to the cap with blue highlighting.

 

The contact spot is flat but our CPU has a convex heat-spreader. This shows up in the thermal grease imprints:

 

Like the junior models LQ310 and LQ315, the Zalman LQ320 is equipped with a single 120mm ZP1225ALM fan which is PWM-regulated in a speed range of 900 to 2000 RPM. You can set it to blow in either direction using the long and short screws included into the box.

The descriptive part of our review is over, so we can proceed to our testing now. The testbed configuration and the testing methods have remained the same as in our previous review, so we won’t dwell on them here. The four products described here will be compared with the best system of the previous review (Thermaltake Water 2.0 Performer) and with the air cooler Phanteks PH-TC14P?. Besides their default fans, the Zalman LQ320 and Thermaltake Water 2.0 Pro were tested with two Corsair SP120 fans.

We also tested the Corsair Hydro H100i Extreme Performance with two additional Corsair SP120L fans taken from the Corsair Hydro H80i High Performance.
