Irons quite useless with MiniFit JR connectors mounted on 12L PCB I would suggest using 1500-2000W heatgun with temperature fixed to 240C. Be sure to add some heat shield in front of capacitors, not to explode them with overheat. Beware your eyes (no joke)

good idea will practice on some older dead cards

I hadn't noticed that before; that's just insane.

Looking forward to this one TiN!

EDIT - Be careful; seems they don't like voltage increases.

Quote:
With a card like GeForce GTX 590, that has so much latent performance, I couldn't wait to try bumping the voltage to see how much I could gain from it.

As a first step, I increased the voltage from 0.938 V default to 1.000 V, maximum stable clock was 815 MHz - faster than GTX 580! Moving on, I tried 1.2 V to see how much could be gained here, at default clocks and with NVIDIA's power limiter enabled. I went to heat up the card and then *boom*, a sound like popcorn cracking, the system turned off and a burnt electronics smell started to fill up the room. Card dead! Even with NVIDIA power limiter enabled. Now the pretty looking, backlit GeForce logo was blinking helplessly and the fan did not spin, both indicate an error with the card's 12V supply.
After talking to several other reviewers, this does not seem to be an isolated case, and many of them have killed their cards with similar testing, which is far from being an extreme test.

With the card dead, I looked for any damage and found one of the 12V input resistors acting as fuses to be damaged (1st pic, no visible damage), so I soldered a bridge on it to bypass it, the card then "exploded" again, this time one of the MOSFETs blew up as shown in the second picture above. This was just an experimental fix to potentially revive the card. If only the resistor was damaged then it should be working fine again, looks like something else was broken and the "fuse" resistor merely blew to protect the card.
EDIT II - You probably plan on frankensteining these, so I do realize that doesn't matter a whole lot. Just showing that their VRM's aren't necessarily up to the task.

Okay, now we have new containers for this new beats.

This is meant to be Classified 590

Compare LN2-powered videocard to air-cooled one



Pots fit perfectly both GPU's on 590, leaving enough space for insulation work and power circuitry enhancements.



Both GPU's connected to NVIDIA NF200 PCI-Express bridge, which splits PCI-E x16 into two buses with payment in latency.



Classified backplate still fits if anybody want using it with LN2 session

Little bit about close-ups for some details :



New pots have enough clearance for PCI-E connectors..



And for SLI bridge for Quad-damage action, for sure.



Quad-SLI videosystem looks shiny with F1 Gemini pot even on single-socket Sandy-bridge LGA1155 platform.



Everything fits good with EVGA P67 motherboard.



I bet production versions of new containers will be anodized black as well.



Black edition FTW



EVGA Classified GTX 590 dual-gun LN2 edition



No need for solder mess with PCIe power connectors!

Let us know if you want to get some of these special LN2 containers in nearest future
Their mount support is not limited to only GeForce GTX 590, but also includes GTX 295 single-PCB version and all single-GPU solutions present on market today.
