  1. CPU overheating to 89 degrees while Rendering 3D

    You really have some cooling challenges in your PC, it will take some work to fix them. First, the stock Intel CPU cooler is inadequate for your usage requirements. That really needs to be replaced. If the CPU temperature is reaching 89C, that is close to or over the temperature where the CPU will automatically throttle its speed down to try to reduce its temperature. If that happens, its performance will be reduced, since it will be running at a lower speed. What do you use to monitor CPU and other system temperatures? Basic things you need to know about replacing the stock Intel CPU cooler: Most if not all CPU coolers that will really make a difference in CPU temperature will require you to remove the mother board from the PC case in order to mount them, unless your case has a large opening in the mother board tray that allows complete access to the CPU socket backplate. Your concern for a new CPU cooler's clearance with your memory is unecessary, your memory is very low profile (given your picture) and does not go up much beyond the clamps that hold the DIMMs in place. The same is true for the two water cooling inlets on the heat sink for your board's X58 chipset. A cooler like the CM 212 can be mounted so its long dimension is oriented either verically or horizontally, and at least one of those positions should clear your memory and chipset heat sink. Do you know if you have CPU power saving options enabled in the BIOS? If not, enabling them will bring the idle temperature of the CPU down without diminishing the CPU's performance when you are rendering videos. One of the main problems with CPU temperature is related to your video cards. They create a lot of heat, and most of that heat normally stays within the PC case. The air warmed by the video cards is then used by the CPU cooler to attempt to cool the CPU. If the air temperature within the PC case is 40C, then the CPU will never be lower than that, even at idle, which seems to be the situation now. I know you have one side of the PC case off and use a fan to push air onto the board, etc, which is a good idea. The dust all over the PC components reduces the cooling efficiency of all their heat sinks. If you cannot find a source of compressed air, you could find a soft drink straw and use it to blow air with your lungs to clean out some of the dust. Just don't inhale the dust, and take the PC outside so the floating dust is not in your home. Or you could VERY CAREFULLY use the accesory hose of a vacuum cleaner to remove some of the dust. I'm not sure what PC case you have, or how many fans you have in it now and their locations. Please describe that for us.
  2. [Official] Nepton Owner's Club

    Hi, just started using a Nepton 140XL, after using AIO liquid coolers from another company. I must say I prefer the design of the backplate, and pump/CPU block mounting of the CM Nepton 140XL over the other company's products. Overall, the impression is one of higher quality than the other AIO liquid coolers I've used. I do have questions, about the power connection to the 140XL's pump. It uses a four pin PWM fan header connection, and should be connected to that type of fan header on a mother board. Beyond that, nothing is specified in the instructions about configuring the PWM fan header on the mother board. Any decent mother board provides multiple configuration options for their PWM fan header's speed control. Those range from Automatic, changing with increasing CPU temperature, to multiple built in settings like Silent, Normal, High Performance, etc. Questions, what is the maximum speed of the pump? Is the pump speed meant to change, slower or faster, depending upon the CPU temperature? If not, what is the purpose of using a PWM connection for the pump? My 140XL's pump runs at ~6700 RPM on a four pin PWM fan header, using the lowest speed setting I have for that header. I can increase the speed setting of that header in the BIOS or Windows utility, but the pump speed stays the same. These questions are pretty basic stuff IMO, for anyone that uses AIO liquid coolers and understands PWM fan headers. Any information would be appreciated.
