just received my Titan Vanessa heatsink from ray99mond.

and as usual, my hands was itchy and i started to bend the fins back into the correct position, so i noticed some fins was loose (not bonded with the heatpipe)

thus i started my stove and put on the heatsink to heat it up to the soldering melting point to begin soldering the heatsink

as this heatsink was fast as dissipating heat and wind was blowing from outside, i was loosing heat fast.....so i set the stove on max fire......

and then i started soldering......then i stood there for a while.....KABOOM !!!

my ear went deaf for a while, then i was like WTF, i got a cut on my abdomen and i look at the heatsink, and the heatpipe exploded !!!

looks like i've burned-in for too long until the heatpipe exploded man !!!

my mum thought i was dead coz it sounded like the stove exploded, and even the flame was put off by the explosion



here is the pic, there are actually 3 heatpipes folded in a " U " shape.
the middle heatpipe exploded due to extreme pressure, and it sounded like pipe bomb man





a section of the heatpipe that was totally launched at my stomach man




and my injured stomach, quite a deep cut, i was standing like around 60cm from the stove and it got me man
it aimed at me man





it also send out molten tin from the base coz the explosion was really a big boom!!
just look at the stove area, covered with bits of tin.





luckily i was wearin specs at tat time or i migh be blind de....look at the specs carefully !!!





and look at my pants, small little stars

after recovering from that, i've removed the useless section of the heatsink.

just look at the impact from the explosion !!! totally pushed the fins inwards !!




and i mounted it on my Mobo, it's still doing well, at 45°C at idle for Barton 2.2Ghz at 1.9V, even my SI-97 couldnt get such low temperatures

aiyoo
wasted a heatsink
hahahah lucky its still working lol

omg!!! thanks for the warning. Heating heatpipe = no no.

warning : heating heatpipe = pipe bomb

Heat+H2O=boiling water la...so its like a pressure cooker. Next time drill some holes to empty the water b4 u start heating it.
Lucky u dun have access to commercial high pressure stove and result a worst consequences.

Nice belly man..tht cut aint deep..jus a minor cut for me...a cut from sharp edges from a cut metal my finger 15mm x 2mm.

bro, if u drill a hole in a heatpipe, then u get a copper pipe, it's no longer a heatpipe.
heatpipe can transfer heat so well because it's pressurized

Thank god nothing serious happened to you. I bet your mom was worried. I felt the tension when I am reading your post.

I see...put ethanol in instead...hehe..will increase the performance...when the ethanol evaporates...it fills up the pipe. wait..cannot la..mus stick to water.

Btw..i dun see wikipedia telling me tht heat pipe is pressurized

lucky thing u have your shirts on.. if not it might have penerated your belly and u would have a hole to drain out excess fat.

and radioactive, 15mm by 2mm aint deep cut.. i've tried 15mm by 7mm slit, by my own teeth on my lips.

Yah..shud have gone deeper..drain excess for free....hahaha..jk

i wore the shirt after i got the cut, but it's scary

hey dont do anything stupid yet, i still got thinking to buy stuff from ya haha....

sur eu got THICK SKIN!!! jkjk

wow.....1st time i heard a HSF explode

AllnGap, lucky u r still here, else LYN will less one contributor for computers modification..and we'll kurang one sifu d.. and thanks for the warning...

OMG! Just knew even metal can explode

Wow...nothing's cooler than itchy hands injuries.

Hope your didi is ok

does he haf 1???
lol....but seriously, does this happen to all heatpipes?? imagine if the processor reach tat kinda temp and the whole heatpipe boom....cant imagine the damage...

Smacks sidenwinderz!!
Kenot see picture kar??



Ps: Heatsinks are not meant to be BBQ'ed. The gas inside expanded due to the extreme temps mar.

oopps....haha....never take such detailed look at the pics...lol...

any idea wat is the recommended temps for the heatpipes?? i mean idle working range?

It doesnt matter coz ure CPU is not supposed to reach even 80C even for a Preshott P4. So nonid to worry bout exploding pipes.

I think its below 100C

lucky u din get killed bro..how am i gona get fans from u

Which cpu u know can reach 100C? heatpipes are usually filled wif water cuz the heat(from cpu) will evaporate the water and condenses at the cooling fins.

But this cooling scientist went to heat it until soldering temp. which is abt 190C...water turns into gas...like a pressure cooker without its pressure valve.

hoho~
time to heat up my mom's stove.

m... next time don't do that again! if u have nothing to do. watch tv or sleep will be better.

hmm.. somehow it left me thinking.. what would happen is someone turn on stove, then leave the whole darn heatsink burn there by itself ??

it's gotta be some pretty sight.

You are a nutter.
Better make sure that you're still in one piece when I come back to Penang next time.... but yeah, the aftermath is just

my didi is still in good shape, thanks for your concern

i think the temperature is more than 300°C, and it's impossible to get that temperature with the whole heatsink at that temperature on CPU alone

if u got heatsink which has got lousy soldering, this is the way to make it right.
find a base (copper/Alu) to heat up and then mount the HSF on the base.

heat up until it's able to melt solder, and then dont heat it up anymore, if you heat beyond that u get a big bang like i did

If the fins or pipes or the base is not manufactured properly then just reject the thing. Everything is machine manufactured and we can't really replicate how it is made.

Anyway it is kind of crazy and stupid to try and fix this. Its just not worth you life just to save a few bucks.

If u r really unlucky, the debris could end up in your skull. Being blind is less of your concern then. Much more for your parents.

it should turn out fine if i had shut the stove way before it exploded.
i've put too much heat on the heatsink

Hmmm..... Since like do some experiment, not take cover yrself for safety?? donno how to happen "Kaboom" after that got mess around .......

Hebat Hebat!!

oke.. this time the police will not fine me for selling this firework alternative this upcoming CNY. huhu lucky you're still in one piece. anyway, no need to post 1st ma. claim warrenty dulu.. huhu...

from the pics. you're shirt looks wet.. your didi was shocked till cry eh.

allngap. from your prediction, if the heatpipe was still oke.. what changes in temperature do you see from the full potential of the heatsink?

what can't kill you will make ur com stronger

terlalu hebat

maybe 1°C or 2°C ??? dont care anymore coz it's good enough

the secret in getting low temperature in this type of tower heatsink is to blow the fins and the base as well.
putting a fan at it's base could lower at least 2°C of the lowest u can get by mounting a fan on the fins.

itchy hands are dangerous man

Very true....itchy hands will do all those things by common sense will not do....i oso got my pair of itchy hands....itchy until open HDD casing to see it work..then remove the disk and see....end up screwing up the drive...but lucky i have not lost all myself...i picked the 10gb disk from my old P2...not my 120gb

hahahahahaaaa

thanks god u safe.... huhuhu..

huwah....

wat is the temp to cause this???

AllnGap.... u r really lucky bro ^^ thx for sharing though

but u still got mood to take all these pic arr ?

haha....

the story continues a year later.........

heatpipe also can kaboom aa??

lol..i was wondering, would the incident where the heatpipe exploded causes that heatsink to function better..lol..

wah............. unbelievable...........it seems the T*l*b*n have fine another good b*mb on hand................

lucky the pipe was quite thin, didnt manage to make a super deep cut.........

i think next time manufacturer put a big warning sign on the heat pipe, do not cook it on the stove.........btw just wandering if manufacturer tested it the same way ?

I was wondering, wat's the content inside the heatpipe? or it's empty at all?

inside heatpipe contain nitroglycerin dissolved in nitrocellulose and a little ketone to in the mixing process. Its formula is, thus, similar to cordite lol

man, that awful! thank God you're okay

For industrial heatpipes may be. For PC usage heatpipes r actually very basic. Most if not all of them contain just plain water in a wicked pipe, that's all. There's no exotic liquids in PC heatpipes.

Water???
Tats bad if it's only water. Means having the heatpipe only serves for cosmetic purposes rather than actually increasing performance?

just read this thread...

so lucky la you.never expected it will blow

you might want to go revisit the "thermodynamics attributes" of water to understand why water is such an interesting stubborn element when it comes to heat energy. that's what make them a good coolant.

oh btw, on an interesting note.. "didi" can also be considered a heatpipe rite?
