🛠️ TOOLS & THINGS TO BUY:
• 🇮🇹 Italian-made molded Gear on EBAY: ebay.to/2FhBCs5
Updated in May 2024. I can confirm the quality is now on par with Tune-O-Gear, which I reviewed here: youtu.be/eC1nUblJpwQ
• EM-30L Grease (AMAZON): amzn.to/2DZRdvX
• Super Lube PTFE Oil 51010: amzn.to/2ANvXI7
⚠️ Only mix SuperLube oil with SuperLube grease, not with EM-30L.
• Super Lube 21030 Synthetic PTFE Grease (NOT Silicone!): amzn.to/3j2xV88
• 99% ISO Alcohol: amzn.to/3WbB5f0
• 4.3" LCD Microscope: amzn.to/46GyNHX
• Anti-static pad with Wrist Strap (16.9x21.6" / 43x551cm): amzn.to/3LBfMi1
• Wall socket Ground adapter for banana-jack Wrist Strap: amzn.to/2Yvq5ge
• Torx T15 with LONG neck (to open Mac): amzn.to/2ScAskx
• Bulldog Clip (helpful to pry off back case): amzn.to/2H7lIhF
• Cotton Swab for head cleaning
• Soldering iron with °F-only LCD & Solder Kit (80W, cheap!): amzn.to/4bQSob2
or
• Soldering Station (120W, ESD safe): amzn.to/30g1Frt
or

🛒 MOUSER Cart to replace electrolytic Capacitors: bit.ly/3fZzuBR
⚠️ Before you buy this cart, check your 1.44MB drive's capacitance values so you can confirm your drive is the same as my 1.44MB drive. NOTE! Not all the capacitors are the same as 800K drive capacitors, so beware if also buying for an 800K drive. You should also consider recapping other boards too so you can add those capacitors to get your balance high enough to qualify for free shipping. I make no commission at all on Mouser Carts. I just provide it to be helpful. See my 800K drive video for details on how to go about recapping, since the location of capacitors is the same on the 800K and 1.44MB drives.

📚 REFERENCE:
• Molycote EM-30L Grease Specs: bit.ly/2UpxNph
• NEVER format 1.44MB High Density floppies as 800K or 400K. 1.44MB High Density floppies are designed to be written with a stronger magnetic field. A 400K or 800K drive will write a weaker signal to a 1.44MB disk, and that will likely develop bit-errors over time. Only use Double-Sided Double-Density DSDD 800K disks in 800K or 400K drives, or use 400K disks in 400K drives. You can use 400K & 800K floppies in Apple 1.44MB "SuperDrives" because 1.44MB drives use a weaker magnetic field when writing to the lower density disks. Just don't use 1.44MB disks in 800K and 400K drives, even if they seem to work.

Composed entirely of MacPaint images from his ground-breaking book, Zen & the Art of the Macintosh, Michael Green used MacMovies from Beck-Tech to assemble this stunning movie animation. When first publicly shown at the January 1986 Macworld Expo, Beck-Tech engineer Henry Spragens was so impressed he paid over $1000 for a 20MB hard drive just to be able to store and playback the movie on his own Mac. This and more can be found at Henrys website here: https://www.audioimprov.com/AudioImprov/Macintosh/Macintosh.html

🙇♂️ Dear Subscribers and Friends,
I sincerely apologize for the delay in releasing my next product video overview. This ZEN Movie video is a smaller work that is my way of offering at least some content to you in July 2021. Ive had some time consuming projects that slowed my filming pace, but more content is indeed coming! Your kind understanding and patience is sincerely appreciated.
I will offer more detailed appreciation at the end of my next video; but for now, I wish to HUMBLY THANK two amazing individuals for their extremely kind and generous PayPal contributions to this channel:
🙏 Mauro Acciaccaferri — a monthly PayPal supporter since March 2021!
🙏 Kai Robinson — who made an extremely generous contribution in June 2021!

![AMD 6970M Repasting & PROBLEM in 2009 iMac 27 [Video Card]](https://i.ytimg.com/vi/n2a8oEI2y6U/hqdefault.jpg "AMD 6970M Repasting & PROBLEM in 2009 iMac 27 [Video Card]
I explain a Radeon 6970M video card compatibility problem used in a late 2009 27 iMac. Repasting helps but doesnt completely solve the sudden power-down problem. (Sorry about the background noise, but thats Japan for you!)
🏥 PROBLEM: The 6970M causes the iMac to suddenly power-off when the video card gets too hot, unlike the stock 4850 video card which would never kill power to the Mac. Before repasting, the iMac would shut-off at around 52°C or 61°C, depending on the software running. After repasting (with Thermal Grizzly Kryonaut on the GPU and K5 Pro on the memory chips), the GPU Heatsink temperature at which the shutdown would occur became 77°C. This is still a problem though because the iMac shouldnt suddenly shutoff at all. I therefore cannot recommend the 6970M in 2009 or 2010 iMacs. I will retain mine though for further testing and to at least be able to use my iMac.
🎥 My previous video on the 6970M: https://youtu.be/9dPsH1zIQMs
👕 Apple T-Shirt worn in this video is a shirt Ive had since my college days, acquired sometime around 1990. Heres a photo showing the back side too: https://cl.ly/95c617

🍎 Apple Forum Discussion about replacement video cards that work in the late 2009 27 iMac: https://discussions.apple.com/thread/3029120
♨️ If your 2008~2011 iMacs video card is dead and youve never baked it before, I suggest you perform the bake before spending the money on a replacement video card. My BAKE VIDEOS are here: https://bit.ly/2UEOf4o
🔥 THERMAL PASTES I strongly recommend:
K4 & K5 Pro Kit: https://amzn.to/38WkEZO

K5 Pro (for chips other than GPU): https://amzn.to/33OIDJ6
& Thermal Grizzly Kryonaut (for GPU only): https://amzn.to/36NMQwu
😎 Fan Control & Temperature Viewer Apps to keep your iMac running cooler I can vouch for all of these:
• Macs Fan Control: https://crystalidea.com/macs-fan-control
• smcFanControl: https://www.eidac.de
• iStat Menus: https://bjango.com/mac/istatmenus/
🛠 TOOLS to open/close 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 its 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 (youll need a handle): https://amzn.to/2vRkUeC
🔦 OTHER ITEMS needed or recommended:
• Anti-static wrist strap (connect wire to earth ground): https://amzn.to/2uSTy74
• Dust blower - Giottos Rocket Blaster Large: https://amzn.to/2OgHHXt
• Microfiber cloth (for cleaning the screen/glass)
• Flashlight (to peer into the dark spaces inside the iMac)
