Newb Qs - i5 3570k to 4.0ish - watts? heat?
Last response: in Overclocking
Hi
I am intending on having a i5 3570k and overclocking it to 4.0-ish.. basically as high as is easily stable, and *can be air-cooled fairly quietly* ("quiet" = barely audible from 4 feet away, in a almost silent room)
the 2 main Qs are, what size PSU is needed for different frequencies, and how much more heat is created
Shows the 3570k's wattage as 77watts.
What would the wattage be at 3.8? 4.0? 4.2? 4.4?
How about the heat increase when going to 3.8? 4.0? 4.2? 4.4?

The PSU isnt a concern unless your running a 300W with a graphics card, a decent 550-650W will cover you just fine.
Power Draw roughly equals Heat Output and both are expressed as TDP, most of the energy going into the CPU is being lost as heat. There is a formula you can use to calculate the TDP of an overclocked CPU, but you will need the voltage it will be running at to get an accurate result.
Overclocked TDP = Stock TDP * ( OC MHz / Stock MHz) * ( OC Vcore / Stock Vcore )^2

Hi
I am looking at using the integrated HD 4000 (no physical video card), and the Seasonic 430w PSU. Plus one 7200rpm hard drive.
Equations 8| That'll take some time to learn.
Is there some approximate rough estimate? Like would going to 4.0 produce twice as much heat as at 3.4, or 50% more...
I'm just wanting some idea of how much it can be overclocked without requiring twice as much cooling.

It's extremely easy, depending on your motherboard. I was playing around with the OC software that came with the ASRock Extreme4 this morning and went from stock 3.4 to 4.1 with a Evo in push only and stayed under 60C under load (used OCCT to test). All I did was click the "+" sign on the interface a couple times...

(the specs are i5 3570k OC'ed to 4.1, using a 212 evo push-only, with a ASrock Extreme 4 mobo)
