Upgrade Update !

Had to make a few changes, due to the fact my 2nd Hard drive was running at 60° and my 1st hard drive was running at 48°.
Speedfan gave me this good news, so then I had to do something about it, which was to look through my box of computer spare parts as I knew I had some small fans from a aluminium tray from a server.
The fans were to wide to go in the Plexus Tray, so I took that out and installed the aluminium tray and fans, which cooled down no.2 hard drive to about 30°.
Unfortunately the fan was connected directly to the power, so they were on constantly, so a bit loud.
This also wasn't doing anything for no.1 hard drive, and looking inside I noticed that I had a space for a Case fan, so thinking I had measured it correctly, I went and brought one from PC world.
I had bought a 80mm fan when I should of got a 92mm fan, so that will have to be returned.
Looking through my spares again, I once again found a 80mm fan, which I have used until I get one that fits ( only one screw holding it on).
Once I had turned it around so that it was blowing air out, it seems to do the trick without the need for the fans running on the hard drive tray.
So what are my plans next ?
Not really sure yet, I do need to try and sort out the wiring, which will improve cooling.
Then it depends if I go for a processor upgrade or a new build, and the trouble with the proccessor upgrade is that it is socket 939, which limits my choice.
