It's soldered!
Hello:
I'm a bit happier that I've got some Alpha's coming Monday... This guy must have been really pushing the temps up pretty darn high -- with a 900mHz overclock and gawd knows how high he had to push the voltage!
This is a common misunderstanding -- the fins are soldered on, which uses melted solder (mainly tin & lead). Welding is much hotter and would be melting a portion of the metal of the base and the fins. I don't think that it is possible to weld copper; only metals like steel, iron and aluminum can be welded (and maybe others like titanium) but not copper, AFAIK.DryFire wrote: I thought it was supposed o be welded to teh base.....

hmm
be interesting how thermalright handles this. They've been pretty proactive on the CS front regarding motherboard mounting.
Looks like a freak accident.
Regardless, something like this doesn't change my plans on an slk 900 u much like the myraid of RMA brandx motherboard posts on ars or [H] wouldn't sway me from that particular mb.
Cheers!

I agree with you, Dukla.... no way that the heat generated by the CPU melted the solder. Pure lead melts @ 325c, the solders that I use in my work are closer to 400c. All the plastic in the area would have been long gone before the solder liquified. There was somebody asleep at the thermometer the day this was made! Most of this kind of soldering/brazing is done in batches in a furnace so I'd suspect that there's going to be more than one of these take a dive off the CPU.

I think not!ct991 wrote:They're also competing for last place on price. Thermalright is much more reasonably priced.Performance. Alpha and Swiftech are constantly battling for first place.
Check out the prices at Newegg.
Alpha PAL8942 $29.99
Thermalright SLK-800U $42.99
I think you'll find the prices are roughly the same anywhere you look.
Granted, Swiftech is the most expensive of them all.
I got my Alpha for $25 from casecooler.com but they don't carry it anymore.

Not AFAIK, but vice versa (Thermalright beating Swiftech with the same 5600rpm Vantec) is at Overclockers.com.johnoh wrote:are there any links to tests where an alpha or swiftech sink beat an slk900 with the same fan on each?

Cold joint
Simple really. The solder that holds it together wasn't hot enough, it's called a cold joint and is one of the major reasons for "infant mortality".
Electronics fail along a curve that looks a bit like a bathtub, it's called a weibull distribution. Lots of early failures due to manufacturing flaws, then a low steady MTBF for the effective life of the item, then, they start breaking again when they wear out.
I think fans have about 100,000 hour MTBF, heat sinks would tend to be more reliable.
Duracel batteries measure failure rates in PPB (parts per billion) I'm guessing thermaltake doesn't have their processes quite as fine tuned as duracell.

And what processor would still be running above 100C? This smells fishy, not burned. there's an awful lot of solder showing. When was the last time you had a hs that big that you certainly would not be able to touch? Where's the mobo software that monitors temps? It's a server, you take precautions right?Pure lead melts @ 325c, the solders that I use in my work are closer to 400c.
