The packaging of the Zalman LQ315 is designed in the same way as the previous model’s except for some variation in color.
We can find the same information on the box but some specifications are different, of course.
There’s a multilingual Zalman manual among the accessories:
The Zalman LQ315 costs $99.99 ($20 can be returned on a rebate card).
This cooler doesn’t differ from its junior cousin much. A close-loop system, it consists of two components connected with pipes:
On the other hand, this system has a thicker radiator and a taller waterblock.
The aluminum radiator is different indeed. It measures 153x120x38 mm, being 10 mm thicker than the other radiators in this review. It has only eight channels and a larger corrugated ribbon with perforation:
So, the distance between the edges of the band is larger by half compared to ordinary Asetek 550LC coolers, which should make the Zalman LQ315 more efficient at medium and low speeds of the fan despite the thicker radiator. We'll check this out shortly.
The height of the pump is increased from 28 to 32 mm:
This doesn’t mean any improvements in terms of coolant flow or something. The pump is taller just because it has to accommodate the integrated highlighting of the letter Z on its cap:
This marketing trick should appeal to fans of Zalman, Zorro, Godzilla, Jay-Z as well as to many other people who just like the 26th letter of the Latin alphabet.
Here’s a couple of photos showing the thermal grease imprints of this cooler:
The Zalman LQ315 has the same fan as the Zalman LQ310:
Its impeller is 113 mm in diameter whereas its motor is 42.5 mm in diameter. The 4-wire cable is 345 mm long. According to our measurements, the fan consumes up to 2.47 watts and has a startup voltage of 3.3 volts. That’s all we can tell you about it.
Besides the blue highlighting of the waterblock, the installed Zalman LQ315 can be identified by the captions on the sides of the radiator:
Now that we’ve checked out the key features of five compact liquid cooling systems, we can proceed to test them in action.
