i just installed this thanks to your video. one question though, how does it work without being plugged into anything?

[mariushmedias]

@jwr257 This heatsink uses heat pipes - these take the heat away from the small square over the CPU and spread it around and over the heatsink blades (fins). As long as you have another fan in the system to move the air around (the power supply's fan or even the fan on the CPU) the fins on the video card heatsink will get cooler air around them and will get cooler and the whole process is repeated See en wikipedia org / wiki / Heat_pipe for better explanation

Where can I buy the heat sinks and tape to apply to some of my chips that get hot?

[mariushmedias]

@capman911 As I'm from Romania, I used Romanian stores... you can get them usually from online stores aimed at modding but they're also available on newegg, Amazon (com, co uk , de, fr - try the one closer to you), just search for "vga heatsink" .. there's also dealextreme com (cheap but wouldn't trust their tape)... in the worst case try eBay. The sticky thermal tape usually comes already applied on the heatsinks.

i'm planning to take off my stock heatsink to reapply thermal paste on the core. do you think the sticky tapes are reusable or do i have to have new ones ready right after i take off the heatsink.

had my card for 2 years now i believe, the temps are idling at 60+ celcius. probably hitting 90+ on load so i'm getting worried.

[mariushmedias]

@Bobobearx Changing the paste won't do much difference, just a few C degrees. The card is by design hot (the fan is kept at low spin) and is tested to run for hours at 100C and over, and will throttle itself down at around 105C.

I think you just need to take off the plastic cover (see the end of this video) and use some air spray (can) or a straw to blow some air and take out the dust from inside the copper "tunnels"

No point taking off the cooler unless you get the Accelero kit and install it.

Congratz bro :)

nice video.

keep it up

Hey I was wondering if you could help me out. I have the same cooler, and I installed everything but the VRM heatsinks onto my 4870 1gb card. The temps have not lowered. MSG me if you can, thanks.

[nikokapo]

@mariushmedias I appreciate the information :) Thanks!

[mariushmedias]

@nikokapo That's how I use it, without any fans on it. I just have an Antec TriCool fan at the lowest speed on the side panel - didn't clean the dust from it in months and it's 43C idle, about 58-60C in full load. Very low compared to 80 C idle , 95+ in full load with dirty stock cooler and much lower than what the 4850 processor was designed for.
