How many % heatsink can help CPU?
 

Dear all,

Can someone tell me how many percentage that heat sink can help to
cool the CPU?

Thanks,

100%, without one your CPU would burn out or even explode.

I can tell you what a good cleaning can do, no percentages...

I was running 63°C a few days ago, I took canned air and cleaned out
the garbage from the vents of the heat sink; it now reads 50°C

Using a heatsink versus not using one?

Lapping the mating surface of the heatsink versus using the
factory-supplied surface? Lapping the die casing, too?

Active (fan) cooling versus passive (radiant) cooling?

Size of heatsink? Material used for mating surface and material used
for transfer to air?

Air-cooled or water-cooled?

The thermal transfer compound (heatsink paste) is used? Whether
properly applied or gooped in excess which actually reduces heat
transfer rate?

Using thermal paste versus thermal pads?


Well, ask a vague question and get a vague response.

Simple math. If you ran the figures, you got a 21% increase in
efficiency, which is supposing that the temperature figures are somehow
based in rock-solid standards and are not capricious. How about we just
say that the CPU go BOOM with no heat-sink/cooling fan.

Between 0% and 100%.

You might want to provide more information.

Different heatsinks can keep your cpu much cooler. How much depends on a lot
of things as others have mentioned.
If you present cpu is running too hot, a better heatsink/fan combo can bring
it back down to reasonable limits (many times just a good cleaning can do
wonders).
Course you could go to a liquid cooled system etc to really run it cool
(very useful with high overclocking).
Perhaps if you could explain why you need to know, more help could be
offered.
PS: Without a heatsink, some cpus would only last less than 10sec, some way
less.

I used to do nuclear physic problems, I could equate the possibility
of a pile going critical, now I just skip the math, let others do it
if they wish.

if your piles get too critical...there's always Preparation H

Rubbish.

Your "math" relies entirely on the scale the temperature is based on.

Assuming degrees celsius you do indeed end up with 21% or so.

Convert the temperatures to farenheight however: 145.4 to 122 gives just
over 15%.

In degrees Kelvin, 336.15 to 323.15: 0.038673211%, almost zero improvement
:-)

The common sense is: the designers put that heat sink there for a reason.
Remove it at you own peril.

The real question is: why would the OP even ask? Does it matter? Would you
remove the "radiator" from your car, just to see what happened?

You seemed to have snipped the part where I addressed these issues.
Doesn't matter anyhow.
