Spec - Sony Vaio VGC-JS4EF all-in-one, Nvidia GeForce 9300M GS, Intel core 2 duo, CPU E7400, 2.8GHz

Running Windows 10, all seems well when first powered up but after roughley half an hour a fan starts steadily speeding up and making more air moving noise (happened with Win 7 and 8 also). This makes it difficult to use as it remains constantly loud/fast. The only thing that changes it is if I put the computer to sleep, the fan noise drops and seems "normal" again after waking.

I took some readings from speed fan just in case and they are as follows-

Startup -
GPU = 43c
HD0 = 23c
Core 0 = 34c
Core 1 = 27c
After 1/2 and hour
GPU = 55c
HD0 = 33c
Core 0 = 43c
Core 1 = 36c

Device manager states the following missing, although not sure these are affecting the fan

Base system device - PCI\VEN_1180&DEV_0592&SUBSYS_9044104D&REV_12\4&1F14738C&0&1AF0
PCI Simple Communications Controller - PCI\VEN_8086&DEV_2E24&SUBSYS_9044104D&REV_03\3&11583659&0&18
Unknown Device - ACPI\SNY5001

Any advice much appreciated
