I inherited a computer that is about 5 years old and have been running it for about 6 months. It has been running very quiet and I have never noticed the case fans running. I decided to upgrade my video card from a GTX 730 to a GTX 1060. The 730 does not have a power connection and the 1060 has an 8 pin connector. After i installed the 1060, the two case fans that blow upward are running constantly and coretemp shows the temp to be about 80C and when I do anything on the computer the temps go up to 95C. I have a Gigabyte Z97X-UD5H motherboard with an i5 4670 CPU. It has a coolermaster lliquid cooler with two fans that blow upwards across the radiator and out the top of the case. I noticed that the vid card fans are not even running. I replaced the 730, thinking the 1060 was generating extra heat or power (it has an 850 PS). After the 730 was re-installed the computer is still running hot and the case fans are spinning at top speed. Could I have compromised the liquid cooler when I laid the computer on its side to work on the vid card? Or could I have done something else? EDIT: Forgot to mention that I cleaned the dust out of the radiator with a can of compressed gas and that did not change anything.
