I assumed snaking would be harder to make. Anyway since the original heatpipes are still almost as hot at the top as the bottom, I\'m sure they could carry more if the top of them was cooled by another heatsink.
I set fire to a strimmer once. I haven\'t blown much up, unless you call smashing the spark plugs in a Renault engine \"blowing up\". All I did as overrev it, assuming that all modern cars had a rev limiter. but then the French are a bit lackadaisical.
Bullshit. It\'s not as simple as traffic on a road, where one junction is the bottleneck and no changes to surrounding roads makes that junction any faster. If the interface to the CPU is limiting heat transfer, and say producing a temperature difference of 20C between the CPU and heatsink block, and then you make the heatsink colder by a bigger fan or a bigger heatsink, you could increase that 20C difference, causing more heat to flow through your so-called \"bottleneck\". Think of it like a garden hose, the width of the hose is limiting the water transfer. But if you increase the pressure, more gets through.
I want to make it run cooler without expense or time.
I\'ll correct that for you, \"it\'s common for people....\" You do like to do things the longwinded way don\'t you? Stacking the heatsink was the easiest way to fix the problem.

Since the heatpipes of each would be very close, the length of normal steel would be minimal.
WTF are you talking about \"normal steel\"???

It would be an odd construction - that had so much free real estate in
that particular direction, away from the heat source.
If you mean the computer case, it\'s not in one, the motherboard sits on
a bookshelf. It\'s a research machine sat in my garage made out of spare
parts, and no case was the right shape to fit a dual server board into.
It is antisocial to operate a fast PC outside an enclosure other than
for testing because it is a broadband emitter of RF interference to GHz.
I don\'t give a fuck. And that does explain why the monitor jumps a bit. There are 5 such open cased machines there. I wonder if that\'s why my neighbour has installed some kind of WiFi repeater in his garden Pissed him off without even trying!
You are starting to sound like a dick who used to post here under another name that I can\'t recall. What was it? You used to blow up stuff and get mad at the people who made it.

You\'d get a better result with a bigger mounting interface to the heat
source,
Can\'t be done, the CPU is a specific size that cannot be changed.
You can get oversize heatsinks using heatpipes to shift more heat from
the CPU to the finned metal.
But the interface between the CPU and the block would be the same size - the area of the CPU.
Yes, you are very definitely not understanding what is going on. If the interface to the CPU was the limiting factor in heat conduction, then you would not get better performance by stacking your heat sinks either.

Larger fans are quieter too. If all else
fails water cool the thing which is what the serious overclockers do.
Expensive, hassle, leakages....
And serious overclockers use liquid nitrogen, or submerse the whole thing in oil!
So you just want to do something lame and pathetic?

coupling the heatpipes to it in parallel, rather in series,
or just by pushing more air.
Heatpipes only work if the temperature of the source exceeds a certain
level.
The top of the current single one feels pretty hot, so the bottom of the
new one would also be.
The way to cool it is use a larger heatsink designed to match the CPU
surface and use the right compound to make the best thermal joint.
I just replaced the fan with a faster one. Lost 20C. I\'d forgotten how shit some fans are. 1100rpm to 4000rpm!
Yeah, it\'s not uncommon for people to rush to a solution before they have all the facts. Still wanting to stack heat sinks?
