nh-d15 bent heatpipes

[HermanT]

can someone explain to me this phenomenon and why and how it happens?

 

I do see some coolers have warped heatpipes, but usually its either all of them or none of them... and here I have 2-3 on noctua, why? whats up?

My NH-U14S has that too. I think its normal

probably overclamped any signs of leakage

Nahh that's perfectly fine, hyper 212 is just like that.

If it doesnt have leakage then you are fine

[HermanT]

hmphhh... looking at screenshots via google shows me that every nh-d15 has same bends on same pipes in the same area...

 

what for?

[MegaDave91]

It's likely crimped...normal thing

[HermanT]

is it daytime down there in america? im surprised to see such lightning responces  at 5 a.m. lol

Only half of the heatpipe ends are bent like that. It is how they are manufactured. There is no performance degradation.

[HermanT]

still weird, every d15 has same pipes crimped at the same spot, how does that work?

since we are on the subject and I dont want to make another post on heatpipes (had a question laying around before)... whats inside heat pipes? Linus said something about gass or something, I always thought that they were solid copper...

They are solid copper unless it is advertised as a special "vapour-chamber" heatpipe design which has water inside.

Heat pipes are not solid pieces; they're filled with a fluid. So the crimped side is likely the side that was filled.

sorry I'll rephrase that... I though they war solid pieces as in not hollow... but they are actualy hollow inside (pipe I guess... my slow logic duh...), hollow filled with air unless otherwise advertised?

yeah, my hyper 212 is crimped like that. and its 10:30pm here in america on the east, and earlier in the night in the rest of it. 

[HermanT]

btw guys, that is some badass badge (case sticker) noctua gives you... its like about 1.2mm (1.0mm -1.5mm) thick... thick iron with printed logo...

Copper heatpipes are solid copper, not hollow, only copper inside.

Vapour chamber heatpipes are hollow pieces of copper filled with air and water.

I dont know if the NH D15 uses vapour chamber or not, you will have to look that up.

if they would use that, there would be no competition lol...

 

thanks!

they are ALWAYS empty pipes, not solid.

They are empty and have liquid, they are sealed without air inside.

I mean i bend my heatsink to remove it. Makes it much easier to remove.

awesome video, thanks!

 

whats the difference with the vapor chamber then... soo many bloody questions...

You are misinformed. Whoever told you that heatpipes are solid deserves a punch in the face.

Also, Vapor chambers (and heatpipes) do not have air inside. Its contains part vacuum and part liquid.

How can you call it empty when there is something inside?

Well personally I wouldn't punch linus in the face, but I'm pretty sure he has said "solid copper heatpipes" at least 2-3 years ago.

Looks like my info is outdated, sorry
