Hey Anyone,
I have this problem with my 2005 G35 Coupe recently and I can't seem to figure out the problem.

For the past few days I notice the fan noise has increase, even at Idling.
After driving for 20 mins. I notice the temperature reading almost peak at Hot.

The coolant reservoir was at max and there was no sign of leakage.

I was going to take the car to the mechanic but they are close today.
If someone has the same experience in the past please comment.

Thanks in advance.
