Noise Levels
When I’ve tested NVMe heatsinks with fans in the past, I always test them with my motherboard’s default setting, shown below. I never bothered to adjust this because at this setting, none of the units I’ve tested ran louder than my system fans at idle – and I like a nice, quietly running system. But I recognize that many of you might be interested in this data and I will record it for all reviews going forward.
Generally, it’s completely unnecessary to run any of these heatsink fans at full speed. You won’t gain any performance, and truthfully this heatsink performs well even without the fan powered on! Really folks – don’t run the fans at full speed. It doesn’t make any real impact other than increasing noise levels!
Stress test thermal results with AIO Cooling
This heatsink was tested with only an AIO on the CPU. Results with air cooling can vary to an extent. For more information about how this can impact results please refer to my recent review of iHTP’s SSD cooler.
For this test, I run a customer IOMeter script that stresses the Phison E26 controller of the SSD as well as the NAND of the device at the same time. This is a stress test run for 30 minutes, and is specifically designed to test the strength of the SSD’s heatsink. Most users will never encounter a workload this stressful.
Reaching only 50C at the end of the 30-minute stress test, Graugear’s G-M2HP04-F is one of the strongest results observed on this system – tied for sixth place in the best out of 30 heatsinks tested!
Conclusion
Graugear’s G-M2HP04-F features strong thermal performance, enabled by two copper heatpipes, aluminum fins, and a small fan. Truthfully, with little bit of modification, this unit could work well to cool a low power CPU. However, the price for this level of thermal performance is “expensive” (compared to other units) with a price of $29.95 USD.
You might want to consider a unit likeID-Cooling’s M15instead. Its thermals are not quite as strong, but still much stronger than common users will need – and it is half the price of the Graugear unit.
