The fan noise is fine unless its on full when you're hitting absolute max temps, then its quite loud.
The drives this originally came with (WD Blue) are ****, and I mean awfully ****.
Even if you're playing MMOs you will go mad because they caused every game I played (including MMOs) to pause for 3-5 seconds every 30 seconds. Basically it made games unplayable. Apparently the new batches come with Hitachi 7200k drives which dont have this problem. So I'am guessing someone mentioned to MSI their 'gaming laptop' did not come with gaming HDs and they sorted it out.
Upgrading the HDs is a piece of ****, 10 min job max.
Flip over the laptop and unscrew all the screws (you'll need a minature screwy to do this) holding the big black panel down including the one with the warranty void if removed bullsh1t sticker over it. Take panel off revealing all the internal gubbings including harddrives. Unscrew them, take off the metal caddy things, put them on new drives, screw them back in, put panel back on...volia.
At bootup press delete to go into bios and goto boot tab. Select the drive you want as boot drive first (this is where u choose the SSD as booty), save and exit, install windows onto it. AHCI mode is fine. Infact IDE mode would be fine also. No need to change any raid options unless you're going to be using it, although these are accessed via its own boot menu after the bios boot menu....if you care...
Forget the hard drive parking fix. More trouble than its worth when you can spend £30-£50 extra for a wd black and be running just fine.
Ram is the same. With the back panel off, center of the laptop, take out the sticks you dont want, put the ones in you do. Job done.
