Hi to all Xtremehardware.com friends, especially to liquid cooling fans! Today, we’ll talk about full-covers again, starting the reviews of these products for Nvidia GeForce GTX 980 video cards.After several reviews published about Nvidia GeForce GTX 780 and AMD Radeon R9 290 waterblocks, it is now time to move on to the next series. The first full-cover for Maxwell (GM204) was offered by Aquacomputer, who sent us an amazing Kryographics GTX 980 acrylic glass edition, nickel plated version. Here the Italian Review [Italian Version].

Test Results

Flow rate and restrictiveness test

As regards the flow rate test, we have made several measurements. We have considered the “Empty Loop” to be a circuit made of pump, top, flowmeter and tray; we gave the pump 12V, which yielded an average value of 404 L/h (the average between minimum and maximum value). We have then added each fullcover to the loop, right after the flowmeter and before the re-entry into the tray and obtained the following results.

Let’s now consider our test circuit, that is the circuit we use to cool our workstation, configured as reported in the above table.

We have made measurements with each fullcover reviewed alternating them in the test system.
We have obtained the following flowrate measures:

The recorded data lead us to say that Aquacomputer Kryographics GTX 980 does not stand out of its competitors as regards restrictiveness; nevertheless, it shows good flowrates. Therefore, this fullcover can be used without problems in systems that do not have very powerful pumps.
