Be curious no more.
*Basic RRod clamp fix. wich means 8x machine screws and nylon washer, 16x metal washers. No heatsink upgrade. no case mod to set the machine screws
*No arctic silver. Had some thermal paste lying around wich i used.
*at stock speed cpu was around 80c. i still can't believe it to be right, but i vent over the sink placement and 'twas still the same.
*tried and trued with 70 fan speed. desibel was reasonably acceptable but after gta session garbage started seeping on screen. changed to 100 immediately.
I'd like to give thanks to you xmugen and all else who helped me out with the jtagging and setting up the software on my xbox, couldn't have done it without you. Many thanks
