I can't remember the room temp and the time I took the screenshot. Did you change the fan speed dependent variable to CPU package temp? If so, put it back on the H100i group (water temp) for now. I also noticed your fans are only turning at 900 rpm with a 34C water temp. If it was 23C in the room and you only had the browser open, that is something to look at further. So, if this was a rather warm day in the house or the screen shot was taken after a long period of running, then that may be a valid explanation. Normally, your water temp will idle about 4-6C over your room temperature, although this is case layout and environmentally dependent. In your screen shot, the water temp is about 34C. However, the H100i v2 Temp (water temp) will remain mostly unchanged, even when presented with actual sustained load, as the heat is not being transferred into the water system. With all of the above, your CPU temps will be consistently high or abnormally spiky when presented with low loads, like opening a browser or other program. The orientation of the backplate is a common cause. Sometimes the pieces don't quite line up right and the fit has to be perfect. This can be a bad application of Thermal Interface Material (usually erratic or random CPU temp readings), but more often is the result of less than optimal physical contact between the two. Any kind of load will cause a sudden rise in water temp and it will remain elevated even after the load ceases.Ģ) The other type of common issue is the physical contact between the cold plate on the pump block and the CPU heat spreader. This is best observed through the H100i v2 Temp reading in the last box on the Link main page. When this is a problem, your CPU temps will appear normal on cold boot, but slowly and consistently rise while sitting idle at the desktop. Generally, there are two types of problems with installing the cooler.ġ) The first is a problem with the coolant flow within the unit.
