So let me get this straight: you take heat from heatsink A and blow it onto heatsink B?
Whose dogshit design idea was this?

its the best design possible to extract the heat to the rear of the PC.
lets see your improved design, Einstein.

Cold air comes in, moves through the heatsink and comes out hot on the other end. Having a fan in the middle doesn't change this. Transferring heat to air requires a large surface area because air isn't that great at moving heat otherwise.

it changes how the heat extraction works. do poeple pat you on the head and call you "special"?

Not really, second fan or not you're still transferring heat from heatsink A to heatsink B

anon why do you think the position of the fan has anything to do with the fact that you are moving heat from heatsink A to heatsink B
Anonymous No.106208850
i'm going to speculate that a shallow heatsink offers less impeded airflow than a deep heatsink, so sandwiching the fan between two shallow heatsinks results in better airflow than putting it on one side of a big block

Here you go dipshit

My design is based on the revolutionary idea that a cpu heatsink must keep the cpu as cold as possible instead of your madeup bullshit "we must move le heat to le back of the case". Your usecase is for servers retard. I am talking ATX desktops.

Think of it as one large heatsink with an extra fan in the middle. Because the alternative is a larger heatsink with no fan in the middle, which would have inferior heat dissipation.

Uhh yea, continuous metal fins conduct heat very well.

>but it's cut in half
Uhh yea, metal fins with a gap in the middle don't conduct heat very well. Hence one half will get hotter and won't even keep the entirety of the base plate at the same temp. Literally half the cpu will get warmer.

This would only be a stupid idea if you had 100% efficient heat transfer from heatsink A.
That would make the air after heatsink A the same temperature as heatsink A, and heatsink B meaning it wouldn't draw any heat off heatsink B.
This is not the case, though.

Not at all, rather than sharing the heat load from both sides of the die heatsink a winds up transferring heat to heatsink

the heatpipes keep things evened out. notice they go from one side, through the base, and out to the other side. the heat source is in the middle of the pipe

do you know what heat pipes are?

The heat from one end of the pipe gets transferred to the other end of the pipe. You'd have a point if the fins were vertical.

>>106209028
Yes.

i suppose i could understand his reasoning if he isn't aware heatpipes aren't just empty/solid copper
>>106209032
if one side got significantly hotter than the other, it would evaporate more liquid in the heatpipe on the hotter side and condense more on the other. the whole point of a heatpipe is to spread heat out. the two sides being joined by a heatpipe means they won't become significantly different in temperature

it's no different if the fan was on one side of a combined heatsink, only an infinitesimally thin heatsink would have no gradient from the fan side to the other side. i.e. you're blowing warm air from one side to the other no matter what you do

You're right. Dual tower coolers are a scam by big cooling to sell more warm.

Firstly, it's not going to be 55C after A. The air is marginally hotter.
Secondly, it's STILL going to be cooler than B, so the transfer is still going to be from B to the air, not the air to B.

it werks better like that vs single block pipes goes into
air circulation around pipes more important 2nd pipe get not air vs 2nd pipe get 60C 140F air.
