The MC14 now receives an upgraded sticky pad with considerably enhanced adhesion.
The MC14 is a BGA memory Ramsink made of forged copper and optimized for convection cooling. It was designed for cooling of memory components such as those found in graphic cards, but it works equally well with motherboard VRM modules , compositing chips, or any SMC in need of superior cooling.
It is a perfect companion to our VGA liquid cooling solutions thus allowing high-end graphic cards to operate in virtual silence.
The MC14 is made of forged copper. The density of the pins has been calculated to offer maximum surface area to increase heat dissipation, while allowing the heated air to circulate freely between the pins.
High quality thermal pads: the high quality Thermattach T411 thermal tape offers excellent thermal conductivity and adhesion to the memory modules.
Quick, safe and easy installation: simply peel-off the protective paper, and press the Ramsink onto the component to be cooled
Ideal companion to the MCW55 GPU water-block
Sold in convenenient pack of 8 pieces.

Performance and specifications
Forged C110 copper
14mm (L) x 14mm (W) x 14.5mm (H)
0.3 oz (8.5 g)
9.0 (including TIM joint)
Maximum recommended heat load
5 Watts per heatsink
We conducted laboratory tests, comparing the MC14 to generic skived copper units such as shown below, and found a 6 °C improvement in component temperature at a 5 Watts heat load.
Test conditions: 5 W heat load 25 °C ambient
For reference, maximum junction (core) temperature in current GDDR3 memory modules is 125 °C (link) Installation
1. Remove the existing heatsink 2. Carefully clean the surface of the memory modules with a degreaser (Xylene for example) 3. follow the easy installation steps below 4. Handle the heatsinks with care when they have just been installed onto the memory. Heat developped by the memory in operations will strengthen the bond of the thermal adhesive.

I hate this tape it didnt work at all. I stuck the heat sinks on and left them overnight before touching the cards. In the morning installed the waterblock and installed my cards so i can cut tubing. Within 30 seconds about 90% of the heatsinks on two cards fell off - gahh. To fix this, i removed the rest of the heatsinks and put a dab of arctic silver 5 on the bottom. Problem solved and no heat sinks have fallen off yet.
I had to cut 3 of these down to size to fit with a GPU water block on an ATI1900XT. In the process I was happy to see they are pure copper. The instructions say to clean the RAM, apply the heatsink, and hold for 5-10 seconds. I did that, held them very tight for 15 seconds, and when I was done I could pickup the video card by the RAM sinks! The adhesive works well and the thermal transfer is wonderful. These RAM sinks work MUCH more efficiently than the Zalman blue ones, and I'm guessing it's the thermal adhesive and pure copper that make them work so well.
Oh if anyone is wondering, with an ATI1900XT you can run without RAM sinks when you switch to water cooled GPU but as soon as you play some games the RAM gets VERY hot and I was crashing. I put the heatsinks on and they get really hot but the system is not crashing in games now.
Although there is some complain about the thermal tape couldn't stick well, I bought it for my 8800gt upgrade soon. It looks really cool and I believe I can solve the problem with Arctic Silver themal paste.
I wasn't sure if I was going to be happy with this purchase or not. I also bought and installed (2)Z**man 120mm fans, Z*lman vf-900 VGA cooler, and a va*tech 4 fan controller. I spent some time and money on this project. But I am not disappointed. My results are awesome. My VGA and mobo temps are so low now it's sick, and they barely climb any under load.
these things are great...bought 2 packs of these and stuck them on various chips on my motherboard..they do the work great althoght if your water cooling you might want to get some airflow in your system to circulate the hot air
