Performance Results

Flow Performance

With the methodology explained and out of the way, let’s see how the CPU-380I block performs first in the flow test.

The CPU-380I is spitting out 10.1 liters (2.67 gallons) per minute and sitting in the third place in our comparison with other top CPU water blocks, which is very impressive.

Let’s check the thermal results now.


Thermal Performance

The CPU-380I was tested with one and two pumps in a redundancy configuration. The two pumps setup is also known as a “Series” configuration. Pumps are set at their maximum speed. This test is to determine which block is more favorable to a high flow system.

The following chart reports the Delta temperature under load. The temperature Delta means the difference between the average memory temperature and the average air temperature. This reporting method reflects the true efficiency of the heat-spreaders cooling capability because it eliminates ambient air temperature variations in the data being compared. 

Astonishingly, the Koolance CPU-380 outperforms all of today’s top blocks in both single and dual pump configurations. The evidence shows the CPU-380 loves a high flow setup, and it surpass the Raystorm and the Supremacy by 0.5°c.

Let’s wrap things up.

    erm, WHAT WE DISLIKED:Fittings & AMD hold-down bracket no longer included.
    AMD have their own separate 380A? lol…


      Blocks used to include both fittings and hardware, that is no longer the case. So consumers aren’t getting the choice in terms of value-added features. It’s either or. I suppose that’s not a problem if you have an Intel or AMD rig and never intended to switch, but for anyone who would, you’d need to buy it separately now; it was included before in the purchase price. I can understand the decision, but it’s also a bit of a “cheaping out” on the part of Koolance. Ideally, consumers should see a price drop to correspond to the lack of hardware no longer included.


    As Jake has pointed out, Koolance uses to included AMD & Intel hold-down brackets in one complete package. Now they available separately. A full metal nickle plated CPU block cost approximate $90-$100; example; the CPU-370 used to cost about $99, Raystrom Cu or Chromed is $95 and EK-Supremacy Fullnickle is $96. Now, the CPU-380i has no brass top or AMD hold-down bracket, therefore its price drop down to $74 but if you compare to the Supremacy then it doesn’t have the best value. Because the Supremacy has brass top and AMD bracket.

    Most people like to reuse their water blocks from one system to another. If you decided to build AMD in six months or a year from now then you can’t use the CPU-380I unless you have to purchase AMD hold-down bracket. When that time comes you might have a hard time to locate the bracket due to the vendor no longer carry the inventory or the manufacture no support older blocks.
