i would still overclock and not let the teacher know i was overclocked
(feed him some mumbo jumbo like.. its TURBO MODE stuck on PermaON!!!).
I dun know how to turn it off!! im talking to ASROCK support but im failing hard... <--- use a bad company with TERRIBLE reply times..
I would probably do this just so i could finish 5-10min faster then everyone because my renduring time is decreased due to the overclock.
Yeah... im a rebel... even my comp-sci hardware teacher i had said he had no way to control me... and just gave me an A.
Final project was PC assembly... i built a full blown LC system.... u see why my hardware teacher gave up.
Anyhow OP..
U dont need an aftermarket sink if ur not overclocking.
The intel stock sink is within "acceptable" values for standard TDP.
I personally wouldnt get a xeon cpu regardless unless the price point was identical.
You have better options to resell a non xeon which is overclockable... that wasn't overclocked... then a straight non ocing xeon.
