I've recently replaced my stock CPU fan with Thermaltake Water 2.0 Performer liquid cooler. Also, I've installed a couple of programs to monitor my PC temperatures. I'm currently using HWMonitor I've used another program to monitor PC temperature and it showed the same elevated temperature. I'm concerned with TMPIN1 temperature. It always seems higher than the others (right from the start up). I've trying to google what TMPIN1 is but had various answers. I'm thinking that it is some sensor on my motherboard and hopefully it is not a CPU. The motherboard I'm using is: MSI Z77A-G45 Intel 7 Series CPU: Intel Core i7-3770K BX80667i73770K Processor - Quad Core, 8MB L3 Cache, 3.50GHz Video Card: EVGA GeForce GTX 670 If anybody knows what the TMPIN1 is or any general feedback is appreciated. I'm including the screenshot.
