i need your help guys to install a couple of iceberg 4 pro heatsinks.
Q1: do i need to strip the iceberg power cable and where do i need to solder to get enough juice for 12v?
Q2: assuming that i have upgraded the stock fan to an 80mm fan (and i soldered the 3/4 pin cable to hdd molex cable to gather power); can i solder the iceberg wires to the hdd molex cable for power or could i solder somewhere else?
Q3: how can i mount the heatsinks to the cpu & gpu?
thanks
Being as I just did this a few days ago I'll give you some tips--

++Be careful when removing the stock hardware. I killed a box by being careless and had to replace it with a spare xbox.
++Buy new thermal paste and maybe even thermal paste remover as well. I use arctic silver 5. The stuff that comes with the iceberqs isn't all that good.
++remember, 1.6 version xboxes need some modifying to do both cpu and gpu iceberqs
++Buy from newegg.com. fast, good price.
1. The iceberqs come with a 4 pin molex adapter that wires into 12v. They are pretty noisy at 12v though. I wouldn't recommend using it. Especially since they do a really nice job keeping the cpu/gpu cool at a normal 5v.
2. I would recommend pulling power off the stock 3-pin power jack for the fan. I soldered the CPU iceberq to the underside of the motherboard on the solder points of the stock fan and plugged the GPU into the 3-pin power jack on top. This method works just fine for me. Solder well, use hot glue or something for a secure connection.
3. In a nutshell, first get the GPU heatsink off. The thermal paste is a little tough, so i recommend heating it up a little first to get it relaxed. An easy and safer way (over prying on the damn thing) is to play a xbox game for a few minutes with your case off... and I even put a piece of paper over my GPU heatsink to reduce airflow so it got nice and toasty. But before that, remove the GPU heatsink clip by pressing down on one end and working the little clip out of the groove. Once the clip is off play a graphics intensive xbox game (Careful not to let it overheat!). Once its pretty warm (should only take a couple minutes) power the xbox off and then pull on the GPU heatsink. If all goes well it should come off fairly easily.
For the CPU heatsink, flick the black part of the CPU clip up and then push down on one side of the yellow clip and use a screw driver or something to work it out of the groove then just give it a gentle pull and it should come right off. Then flip the mo'bo over and take pliers and twist/break the little plastic clips holding the plastic heatsink brackets in place. Push the plastic black things from the back until they pop out. Again, don't use a ton of force and be careful. Do this for all of the plastic pins and presto!
Mounting the iceberqs- clean off the stock thermal paste the best you can (thermal paste remover would be a good idea), then put a little thermal paste of the CPU and GPU chips. NOT A LOT. I even used a credit card to scrape off excess paste. Make sure the chips are thoroughly covered with a thin layer. Put the iceberqs on top of the GPU and CPU. You'll notice the GPU has holes lined up with the iceberq's screw holes. (VERY convenient i'd say). You can use your mo'bo torx screws to hold the GPU in place. I didn't want the iceberqs grounding on the metal undershielding so I broke off the metal tabs under the fans and put electrical tape in the hole.
As for the CPU, its trickier. Here's what I did: I used the iceberq's "easy install" clips. They are little black plastic spring-loaded cylinders designed to go in a hole and hold themselves in place. But they are too small for the xbox's screw holes so I snipped the bottom part where the tiny clips connect to the main cylinder so they can expand and flatten out all the way and hold themselves in place. (I broke two, they are very fragile) I pressed the iceberq onto the CPU, put the modified "easy install" clips in each hole, pressed down and applied hot glue to the underside where they stuck out...making sure to keep pressure down on the clips so they would be resting on a dab of glue, making it so the iceberq would be firm in place closer to the CPU itself. I let it dry a little before letting off. Then did the same for the other hole on the CPU and there you have it. Slick cooling at last!
Hoping I'm not forgetting anything
Good luck to you. feel free to ask any questions
