Re: CPU fan doesnt speed up much under load
You are not going to be able to Overclock any more than you have with a Stock Intel cooler...
The Fan on the stock cooler is only rated at 2000rpm so you are already 33rpm better than spec.
and 3Ghz isn't an overclock really on a 930 CPU... the base clock on a 930 is 133x21 which is 2.8Ghz and with turbo enabled gets you 133x22 so 2.93Ghz... with your clocking down the ratio and bumping up the frequency you're speeding up the RAM a little but in day to day use you won't notice anything.
if you want to overclock better you need to upgrade your cooler. how high of an overclock are you thinking? and please don't say as high as it will go because you can get good air coolers that will get you to 3.8Ghz for 24/7 use for under $100. a good boxed Water Cooler could get you to 4.2 maybe 4.5Ghz for 24/7 use if you have a golden CPU for under $150...
it's a rarity to see anyone above 4.5Ghz for 24.7 use but when you do they're running custom water cooling kits that range from $500+ and are quite a bit of work to get setup and sometimes maintain if not configured properly.
So I'll ask you again how far to you want to try and get it?
