CPU temperatures within limits? – Thermal Grizzly, Thermalright, Jeyi and Feng Zao LGA1700 frames in comparison test

枫造 (Feng Zao) Fiberglass Frame

The manufacturer Feng Zao, unknown at least in the western world, is the last opponent in today’s test. This frame, unlike the others, is not made of aluminum, but fiberglass – effectively like a circuit board, only without copper. According to the Taobao product page of the frame, it is probably also available in aluminum, although the Google translator’s conclusions leave us in doubt here.  

Since Taobao does not ship directly to Europe, the only way is through a proxy store like Superbuy, which buys items in Asia on behalf of customers, has them shipped to their Chinese warehouse, and then ships them internationally from there. However, the total cost is still less than 15 euros. In addition to the frame, the scope of delivery only includes a Torx screwdriver.

The frame itself looks relatively rough in terms of workmanship, as the individual fiberglass layers can be seen.

The caliper confirms the first visual impression with up to 0.07 mm variance in the thickness of the frame. Based on the results of the Jeyi frame, this already clouds the expectations somewhat. 

The thermal paste print, on the other hand, is among the most consistent out of all the frames tested, with only a slight loss of pressure in the bottom quarter of the CPU.

In the tests, the Frame can actually convert the supposedly good contact into cooling performance, with impressive 6-7 °C lower temperatures than the Intel ILM. The RAM-OC is also stable after the first retraining and that with completely foolproof assembly without special torque. One possible explanation for this would be the relatively flexible material of the frame, which distributes the contact pressure along the IHS more evenly than frames made of aluminum.
