Compatibility and Installation Tips
Thermalright Venomous X in its standard configuration is positioned for Intel LGA775/1156/1366 processors. However, it is also possible to install this cooler onto AMD mainboards. In this case you will need to purchase an additional retention kit. Venomous X step-by-step installation is described on a separate page of the official company web-site. Besides, you can also download a PDF file with it. We also decided to check out the main installation steps, especially since in our opinion it is the key peculiarity of the new Venomous X cooler.
So, at first you have to take a universal backplate and insert the threaded retention spindles into the loops on its ends. You must use special plastic clips: just put them over the spindles and insert in one of the three locking holes in each corner of the backplate:
I believe that you have already understood that each of these holes is designed to match LGA775, LGA1156 or LGA1366 socket. This is what the assembled backplate looks like:
The thumb-screw on the right with a spindle on one end and a silicone washer on the other should be used to tighten up the retention plate:
After that you place the steel retention frame over the spindles and tighten the thumb-screws. There are four mounts coming out of the frame that will hold the retention plate pressing the cooler against the mainboard and processor. Note that there are four of them, which means that you will be able to turn the cooler any way you want without removing the retention frame and backplate. Now all you need to do is apply a very thin layer of high-quality thermal compound onto the CPU heat-spreader, push the retention plate between the cooler heatpipes and tighten the spring-screws with a screw-driver or enclosed wrench:
But that’s not all yet. This when the most interesting things begin. There is a large knob in the center of the retention plate that serves to adjust the pressure between the cooer base and the processor heat-spreader:
By turning this knob clockwise with the included wrench you can increase the pressure from 40 lbs (18.144 kg) to 70 lbs (31.752 kg). According to Thermalright engineers, this feature improved heat transfer and processor cooling efficiency. I have to admit that it is a pretty interesting and unique solution that we haven’t yet seen in any other CPU cooling systems. I would also like to add that when you are tightening this pressure knob the cooler retention panel is lifted up above the base that is why the cooler may actually turn on the processor. To avoid it, please make sure to hold Venomous X when tightening the pressure knob.
The final touch in the Thermalright Venomous X installation procedure is fans installation. You can attach one or two fans using the four silicone strips and four wire clips included with the cooler:
Thermalright recommends installing Venomous X in such a way that the airflow could be directed towards the back of the system case (perpendicular to the PCI-E slots):
It contradicts our theoretical assumptions that the preferable cooler positioning would be with the heatpipes going along the LGA1366 processor die. That is why before we proceeded with the cooler efficiency tests, we checked out its performance in two different installation positions:
Although in the first case (as shown on the left) the heatpipes were directed along the processor die, which is considered less effective position, Thermalright Venomous X performed 2°C better than if installed as shown on the right. During our comparative tests we checked the performance of Venomous X equipped with one fan rotating at 1200 RPM and with the case fan disconnected.
