I didn't want to comment at first, but after the arrival of the product, there was no plastic film on the whole package box. It should have been opened. The package box had tearing marks. Considering that there was no reason to be serious in seven days, I was not serious. Then the fasteners were extremely simple, and a few screws could not jam the gusset plate (I have not seen such a difficult fastener in 15 years of installation). How strong can I manually tighten the four fixing screws?One thing to say, this star I gave has a fairly good heat dissipation effect. The pressure of 14600KF is 4-5 degrees lower than that of more than 300 360 water-cooled stars!But this fastener is worse than the 30 yuan 4 copper tube. I suggest you report it to the manufacturer. The 400 yuan radiator is not as good as the 30 yuan accessory!
