Overall Score 4.1  

The Cryorig H5 Ultimate is a very uniform and easy to handle cooler. Unusually the H5 looks like its only capable of one fan, but that’s not the case. Cryorig include the rubber and clips to mount a second fan, but with the XF140 included as standard, it’s probably not going to be an issue.

The unique Hive Fin features gives the cooler a flat side, and the tops and bottoms are capped with what is essentially cowling.

There are four 6mm heatpipes running through the base plate. From the pictures below, you can see a machining effect from the finishing process after manufacturing. 10 years ago this would have been an issue, a surface that’s smooth transfers the most heat.

These days, and with all examples we test, the technology is so good, it has almost been factored out of the equation. This surface is smooth and uniform. If you rub thermal paste into the base plate before mounting, this will fill a good number of scratches or imperfections that may cause performance issues. Installation is not an issue, it’s the same as the Cryorig H5 Ultimate CPU Cooler.

Test Set Up

We tested the Cryorig H5 Ultimate CPU Cooler for sound and cooling performance using an i7 LGA2011-v3 set up. We tested two configurations, stock and overclock both with turbo.

Software used for load tests and temperature capture;

We ran the AIDA64 Extreme stability test in 30 minute batches and recorded the results. We used the Core Max result as there was typically a variance across the cores of a couple of degrees. We only selected the cache, FPU and CPU tests, so no other component would generate impacting heat during the tests. We always “run in” our CPU cooler installations, essential to maximizing the performance of the cooler before testing begins.
