Re: lets see your...
I would recommend refitting the H100 block then.
Just so you know, some CPU's might only use one core if windows is just running in idle to save energy.
Depends on the mobo, CPU type and windows / software settings and what ur doing on the pc.
My core readings also are a few degrees off compared to the other cores.
Only way to know is to check :)
If ur running out of space then obviously you want a regular HDD.
So that sounds like a upgrade you will have to do soon anyways.
If you go for a 1Tb drive you will have plenty of room for a fresh windows install and the rest of ur stuff.
This since a SSD is not going to be a option finacially since they are a dollar for every Gb lol
So i'd say u'd get what ColonelMyth picked: HDD
Has all the right numbers, assuming ur mobo supports SATA 3 transfer speeds?
Lateron you can get a small SSD like i did if needed.
