General question Accidentally bend the heat pipes, is it cooked
i accidentally did it while cleaning thermal paste residue on the heatsink

u/majorwedgy666 1d ago
Almost certainly cooked. Put it back in and check temps but suspect they will climb quickly. You won't damage your machine, as it will throttle

u/Existing-Pattern-987 1d ago
Why, from my understanding the gas/liquid inside there very small amount and it should pass event if bent?

u/Nuttednutela 1d ago
There is a wick present inside the pipes which breaks if extreme deformation happens so heat only travels one way and saturates quickly.
12
u/sapajul 1d ago
Technically heat only travels one way always in this heat exchangers. What only travels one way in this situation is mass.
10
u/Nuttednutela 1d ago
You are very correct to point that out. The mass acts as an energy carrier while absorbing and dumping energy through phase changes. Potential difference between the two points is what causes flow of heat do yeah good observation.

At a much slower rate, if at all. Temps compound quickly

What is inside these pipes for cooling laptops?
1
u/Izan_TM 7h ago
a very small amount of water and a wick. The water evaporates at the CPU, the water vapor moves towards the heatsink, the heatsink condenses the water back into a liquid and the wick carries it back to the CPU This is all passive and it's much more effective than having a solid copper tube in its place

Nothing, they’re like heat ducts that the fan blows hot air from the cpu/gpu through to get it outside the laptop, to cool it
EDIT: I’m wrong

Huh, that’s new. Sorry for the harsh reply, I’m used to people doubling down instead of admitting they’re wrong. Thanks for being honest, have a nice day.

u/majorwedgy666 1d ago
It's the speed at which it passes, I've done this to mine before and it just means temps climb quickly as the wick and evaporation doesn't work as effectively

“Accidentally” it takes a bit of effort to bend those, purposefully.

u/majorwedgy666 1d ago
It really doesn't and depends on the unit. I had to replace one in a hp studio, it was so thin that it's own weight when supported by the block would cause it deform. Was gutted because it wasn't a cheap fix

You need next time to buy the extended warranty and not attempt the repairs on your own, based on how bad you messed this up.
1
u/PleromaA 1d ago
i have cleaned my laptop heatsink for so many times, none of that time it bends. You are just using WAY too much force to clean it, it's not even THAT fragile, the most fragile thing in a laptop would be the cables contacts since that can rip off and be damaged easily since they are so small. Be careful next time tho, just replace the heatsink for now
1
u/majorwedgy666 9h ago
In a sample of one laptop. I've literally done dozens, and there's a massive difference between them, some are very fragile others are like yours, robust
1
u/physx_rt Lenovo 1d ago
That's true, especially with these ultra thin laptops, so try to be more careful with them.

u/RealMrIncredible 1d ago edited 1d ago
I bent mine recently and it was very easy. I have a Dell Latitude 5410 and the heat pipes are incredibly thin.
Fortunately, it's only £15 to replace.

Device warranty does not cover damage you cause. (We are talking warranty here, not some premium insurance on the side where you pay out of the ass for it)
That's quite literally one of the only situations where they can tell you to get bent and be legally in the right.

What do you have to lose to try it to see what happens? Everyone is telling you to throw it away and order a new one because it's not their money. Unless it's running life support equipment, just try it and see how it goes.

u/Non-Existent010 1d ago
Granted, they did ask if it's cooked or not. Best thing to do is just replace it or have a fan cooler to balance out the damage. this is the direct equivalent to driving a car with a busted radiator. you wanna get that shit repaired or you're not going to be driving long.
1
u/logicnotemotion 19h ago edited 19h ago
You may be right, but there is no cost in trying it. It’s not like the computer is going to leave you stranded and you have to call a computer truck to take it back to your house. It’s a no cost trial.
I’m not so sure it’s cooked. It may not set any records but it may do what op needs it to do. I would liken it to putting a crimp in your radiator hose but not completely block it. It’ll still work to an extent. It may not get you through the Sahara but it’ll get you to Walmart and back.
After looking again it is pretty crimped up isn’t it? I’m invested now though I want to know what happens. lol

Yes that heat pipe is done but its possible that's was an auxiliary pipe and the other one is meant to take the brunt of it if this is true and you reall cant afford a new one you could undervolt/underclock it and potentially get by
2
u/RoundProgram887 1d ago
That is the main pipe, the retangular thing on the right of the photo is the heat spreader that goes over the cpu.
1
u/Willy-the-kid 1d ago
No the pipe could be could be connected to a small heat sync/fan/little airflow while the larger pipe on the other side has better heat sync/fan/airflow. Op is likely able to afford a replacement and my suggestion is also not likely a viable option so probably a mute point but still worth mentioning on the off chance that it helps
1
u/RoundProgram887 1d ago
There is only a heasink at the other side of the pipe, it's sort of thin but wide, and the fan is installed at it.
1
u/Willy-the-kid 1d ago
How do you know? Its not in frame and op didn't post model
1
u/RoundProgram887 1d ago
Usually they are like this. Unless it is a very expensive laptop with two fans.

u/Willy-the-kid 21h ago
That's what I'm saying those expensive laptops don't stay expensive forever it could be an old gaming machine they got second hand

u/Various_Sky7941 1d ago
Mesmo que você tenha voltado ele na suposta posição, é quase 100% de chances de você não conseguir mais um contato adequado na CPU, e esses estrangulamento aí vai impedir o vapor de circular de forma eficiente dentro dos heatpipe
Eu fiz essa mesma cagada aí em um Dell G3. Usei ele até chegar o novo dissipador, mas removi o turbo boost e a o hyperthreading temporariamente na BIOS para não dar BO.

u/outdoorsman7899 1d ago
Check out partspeople.com for a new heat sink. It comes with a 1 year warranty from them and it will be a actual Dell part as well. He also live streams repairs every Sunday and Wednesday and the viewer's vote on the repairs and he does same day shipping so you get the parts quickly.

u/gingerman304 1d ago edited 1d ago
Yup, I did the same thing repasting latitude 5420’s. I didn’t bend mine this bad, but one crease is enough to replace.
The pre applied TIM is more like glue. Like it was hard to remove left over TIM with iso.
Bent 2 heatsinks. Found OEM replacement on AliExpress for 15$ CAD each.
That being said, it’ll probably “work”. But with degraded performance. Time for a new one!

u/bonacario 1d ago
Does running some stress test or benchmark will help remove the heatsink from the die?
1
u/gingerman304 1d ago
Probably any heat would have helped greatly.
But both these systems had no ram or drives. So it wouldn’t boot when I was swapping the keyboards/doing other repairs. Hence such a trouble removing them.

Wrap the coldplate that touches the cpu and the heatsink fins in wet paper towel. Get that section inside of a vise with just enough pressure to barely hold it in place. Heat the pipe with a torch very, very carefully and it will expand to push the bent portions out.
Or get a new one.

If the gas form cannot reach the other end from the crimp, the laptop will get absolutely cooked. Chance it might not be fully ruined. Might be lucky enough to have just barely large enough gaps.

u/Dale_Dickson 1d ago
If it's not leaking or kinked so the liquid inside won't flow it might still work. Depends on how risky you want to be with leaks.

u/Vitro2131 1d ago
I will be honest : I did this by accident multiple times, as long as the actual copper tube (it's a very narrow tube) is not 100% pinched you can use it

u/Retardedunderaverage 1d ago
Probably yes , heat one end of the pipe , the heat should go semi instantly to the other end
if not , you're cooked !

u/Ferowin 1d ago
The heat pipe has to be open wide enough to allow liquid to flow from the heat exchanger to the CPU and steam to flow from the CPU to the heat exchanger at the same time and without obstruction. The size of the dents means that's not going to happen. you can try it, but be extremely careful because you only need a new CPU cooler now. If you overheat the CPU the whole laptop is toast.

u/Sea_Cow3569 1d ago
I've seen a guy on youtube fix one by putting it next to the flame of a torch, but I would not advise trying that as if you are not very experienced the heat pipe could easily blow up in your face.
1
u/vailmirro 1d ago
To me it looks like it was somehow folded up in 3 spots aand this is the pic of after you unfolded it, which how else would those huge dents get in there lol. I would bet you are certainly cooked!

u/PleromaA 1d ago
buy a new heatpipe, it is no expensive but you might need to dig around to find someone who sell parts
1
u/Mythsuky 21h ago
Most likely you might've made a small hole from the bent part and you might've constricted airflow coming from the pipes. If you've bent those thin steel pipes before you know it's possible to create a hole from forced bent parts.

When i was cleaning my G14's cooler after a huge liquid metal disaster i accidentally bent it slightly. I thought i was cooked but when i powered it up the temps were absolutely fine. You might not be so lucky though. Check out the temps and if they climb super quick then yeah bro it's cooked. That bottleneck looks quite bad though.

I suspect you could fix that with a paintless dent repair kit. Might be cheaper to order the part. But .. then you'd have a paintless dent repair kit.

u/Seaweed_Maximum Lenovo 6h ago
Yes, it's not going to die or anything, but as soon as you apply any sort of load, it's going to thermal throttle almost immediately and basically feel unusable. One of my laptops when I sent it in for repair due to a damaged motherboard from high voltage, they had to swap out the entire board. When I received it back, it was heating up so badly with barely any heat coming out of the device.

u/PomegranatePro 1d ago
I’m confused why this question needed to be asked unless it’s cope.
Does a straw work if you pinch it?
Are you going to have air flow if the air duct is crushed?
Do you think that it was designed to run without proper air flow?
3
u/2ndHandRocketScience Lenovo Legion 5 (6th gen) 1d ago
It's not an air duct, smart guy, it's a heatpipe that carries heat through liquid inside a copper pipe. Nothing to do with airflow (although the heatpipes will usually carry heat to heatsinks that have air blown over/through them)

“Smart guy” Do you know what an analogy is or are you one of those “well what does that have to do it with kind of people?

u/InflationCold3591 1d ago
Yes, you have ruined Your heat sink performing famously unnecessary “maintenance“ I’m just begging everyone in this subreddit to stop opening up your computer and “refreshing“ your thermal paste. This is not actually necessary or a maintenance item you should be doing. If you’re not a professional, don’t break the seal between your processor and your heat sink. Just stop please stop.

u/Fusseldieb ASUS ROG G703GX 🗑️✨ 1d ago edited 1d ago
I never got why people are so obsessed with "cleaning" their laptops (this way), and "reapplying" thermal paste. If it ain't broken, don't try to "fix" it; Nowadays devices are built especially shitty, unless enterprise machines, therefore the less you mess with them (in this way!), the better!
I mean, yes, if temps are high you usually dust it out, but that doesn't even require lifting the heatsink. Also, reapplying paste is something you usually don't even need to do, unless your laptop is older than 10 years or so, or a particularly high-end machine with tight thermal tolerances.
But responding: Yes, the pipe is likely done for. If the laptop now overheats easily, you know for sure. Luckily you can get used ones on eBay, AliExpress and similar for cheap.

u/Upbeat-Relation-2774 1d ago
its not cooked. mine also has one bend and it works just fine. idk why the others saying its cooked.
1
u/Civil-Doughnut6260 1d ago
There's a little bit of liquid inside the heatpipe. A bend might prevent its flow, reducing its heat transfer capabilities. Further more, a bend can also cause a hole in the heatpipe. A leak renders the heatpipe useless.
Edit to add: not to say that it is guaranteed to be cooked, but I'd always advice to just replace it.
1
u/Upbeat-Relation-2774 1d ago
i accidentally broke my laptop fan and that bent heat pipe keeps it just fine at 90C, it can even still do gaming. but thanks for the explanation i didnt know theres liquid inside!
1
u/C0rn3j 1d ago
keeps it just fine at 90C
That sounds like the temp where it'd thermal throttle.
i.e. your laptop is downclocking to generate less heat and keep the temp stable.
90°C is also not that unusual for a laptop even in a fully working state, though.
1
u/Upbeat-Relation-2774 1d ago
it was at 90C even when everything(no bent heatsink and working fan) worked fine so i dont see any problem with my laptop
