Late 2009 iMac 27" Video Card Repair [4850 Bake]

This is my 1st bake video which shows motherboard removal. Watch my 2nd Bake Video to do the bake WITHOUT removing the motherboard (and read the text description under that video too):    • Late 2009 iMac 27" Video Card Repair ...   💁🏼‍♂️ Have success?

You'll need an iFixit account but it's free & easy. https://bit.ly/2nCnNan 🤔 Think the bake is crazy? Note the NeXT motherboard was also baked (31m56s):    • Steve Jobs Unveils the NeXT Computer ...   🛠 TOOLS to open & close the iMac: • 2 strong suction cups for front glass removal: https://amzn.to/2tkcmvJ • Torx T10 for LCD removal (T9 works but T10 is best) & T9 for video card removal. The following kit contains more than needed for the iMac, but it's highly rated, has grippy handles and magnetic tips, and no 1 month+ wait from China: https://amzn.to/2UCaurK or Alternative kit, WRENCH style (cheaper): https://amzn.to/2wIgWWe or Alternative kit, BIT style (you'll need a handle): https://amzn.to/2vRkUeC 🔦 OTHER ITEMS needed or recommended: • Thermal Pastes (2 types REQUIRED!) K4 & K5 Pro Kit: https://amzn.to/38WkEZO or K5 Pro (for chips other than GPU): https://amzn.to/33OIDJ6 & Thermal Grizzly Kryonaut (for GPU only): https://amzn.to/36NMQwu • Philips #1 "+" screw driver (for RAM door): https://amzn.to/38VWOgK • Anti-static wrist strap (connect wire to earth ground): https://amzn.to/2uSTy74 • Dust blower - Giottos Rocket Blaster Large: https://amzn.to/2OgHHXt • ISO Alcohol Spray 99.9% (to remove old thermal paste): https://amzn.to/3hD0fOJ • Swabs & Tissues (for cleaning off the old thermal paste) • Microfiber cloth (for cleaning the screen/glass) • Flashlight (to peer into the dark spaces inside the iMac) • Aluminum Foil (make feet to raise up video card in oven) • OVEN set to 200°C/400°F (without which, this repair is in vain) • Time & Patience ► I used a Samsung EVO 850 1TB SSD to replace the stock Apple hard drive, but the 860 EVO or Crucial MX500 are equivalent. To use an SSD in late 2009 27" iMac, you'll also need a special mounting bracket and a separate temperature sensor: • Bracket: https://amzn.to/37Zn4qg • Sensor: https://amzn.to/3b3knWU • EVO 860 (1TB): https://amzn.to/2RKem9M or • Crucial MX500 (2TB): https://amzn.to/3bxHybf 💵 AMAZON pricing is exactly the same even if you don't use my links, but if you do kindly purchase within 24 hours of clicking my links, I receive a tiny commission (TINY!) which helps to support this Channel. NOTE! If you add above items to your Cart but wait more than 24 hours to purchase, I receive no commission. 📷 4850 Card Photos (cleaned): TOP: https://flic.kr/p/RjLLCd BTM: https://flic.kr/p/RjLKGf ♨️ I baked the Radeon 4850 video card at 200°C/392°F for 9 minutes. I chose 9 minutes because after reading much about this subject, some people said 8 minutes and others 10, so I chose the average. ‼️ If you use Arctic Silver 5 like I did, don't use too much because when the heatsink presses down on it, excess paste may spill onto the tiny capacitors surrounding the GPU and the capacitive nature of that paste can cause problems. Arctic MX-4 which is not electrically conductive, so you can use that instead on the GPU. But I still recommend getting the K4 Pro and K5 Pro dual paste kit because you need a thermal pad replacement for the memory chips on the video card. 😎 Fan Control Apps to keep your iMac running cooler. I’m using both on different Macs and can therefore recommend either of these: • Macs Fan Control: https://www.crystalidea.com/macs-fan-... • smcFanControl: https://www.eidac.de 💁‍♂️ Most people in the Comments section who tried the bake find success. Few have serious problems. Those with problems ask and I try to help. Several people have said "you don't need to remove the motherboard." My answer to that is, "yes you do if you want to change the BR2032 battery on the back side of the motherboard." Even if you don't think you want to change the battery, at least remove the old one. Even lithium button cell batteries leak after many years of being installed in electronics. And for those of you who don't care about any of that, simply watch my 2nd bake video to see how to go about the bake WITHOUT removing the motherboard. ►►► July 11, 2017: My 1st bake lasted only 4 months. What inspired me to do the 1st bake was another YouTuber who did the same repair and who said recently his iMac had been running fine for 17 months since the repair as of Feb. 2017. The GOOD NEWS is my 2nd bake lasted 2.5 years!
