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

JEYI 12th Gen CPU Bending Corrector Frame

The product of the manufacturer Jeyi already reminds of the Thermalright Frame in the outer box. The product page and the price of 5-10 Euros on Aliexpress are also very reminiscent of competitor products.

The scope of delivery includes the frame, a warranty certificate and a Torx key as well as a thermal pad. 

The frame itself looks like a hybrid of Thermalright and Thermal Grizzly with black anodizing, white markings, and black plastic spacers on the bottom. At least theoretically, this should be a good omen for the test of the “noname” frame.

However, when comparing the thickness from corner to corner, the Jeyi Frame is already much more inconsistent with a difference of 0.04 mm and visible differences in the height of the adhesive layer between aluminum and plastic.

The TIM print reveals that the Jeyi Frame at least improves the situation compared to the Intel ILM. In the upper third, the CPU seems to sit much higher here, with more contact pressure between the cooler and CPU than in the two lower thirds of the CPU.

Unfortunately, the Jeyi Frame falls completely out of favor in the test results. It doesn’t matter if the screws are hand-tightened like on the Thermalright frame, which corresponds to about 0.15 Nm here, or if they are already stopped at 0.1 or 0.05 Nm. In any case, the RAM cannot be stabilized and in the Prime95 stress test Worker crashes after a few minutes

Even in a short test with the included thermal pad, with consequently higher contact pressure, the result does not change. The temperatures are even worse, which makes replacing the ILM completely absurd. Unfortunately, all this does not fit at all with the Jeyi BCF.
