Are you file sharing/downloading/uploading? That raises the HD activity resulting in increased heat. The HD I have in my Z70va never goes past 55, so if yours is constantly around 55-60, then it might not be normal.
Just try to clean up the old thermal paste on the heatsink and put some new one on the top of the CPU. Contact your local store to ask for a CPU thermal compound, Arctic Silver is a famous brand name for CPU thermal compound maker.
You could get yourself a cooling pad. Some people have reported very good results. Thermal paste is over rated sometimes. The stuff they already use on your heatsink/cpu is ok. The best thermal paste only lower temps by a couple of degrees when stressed.
If you do plan to apply thermal paste make sure you know what you're doing and to remove the old thermal paste cleanly with Isopropyl. Then apply a very fine layer of Artic Silver 5 or similar.
I am having the hard disk "overheat" problem according to NHC for the first time just now while gaming. I have had my z70va for about 7 months now...no problems until now. The ambient temp is no higher than it usually is. Nothing else is reading higher than normal. Any thoughts? Thanks in advance.
I just posted this in another thread, but I just had mine (z70va 5400 rpm seagate 100 gb) overheat for the first time in the 7 months I have owned it. I was gaming, but nothing is different than any other time I have gamed. Any thoughts would be appreciated. Thanks!
