There's been a slight increase in noise since I installed my 3rd-party RAM with heatspreaders, and I'd like my Mac Pro to run as quiet as possible, so I've had a look at these:

Has anyone got any experiences with them? Copper or Aluminium? Any suggestions for placement? These are 5mm deep so should I fit them front and back?

I'm assuming it would be better to place them with the grooves horizontal to better channel the airflow from the fans.

I'm sure some manufacturers must produce heatsinks of the same dimensions as Apple's -- I just can't find any.

I have 4 copper ones on each of mine. I believe for metal to metal copper is better, but metal to air aluminum is better. I just bought the only ones newegg had in stock at the time.

So what ram should I buy, and if it doesn't come with heat sinks, which should I buy?

Personally, I'd hold off until someone tested the memory running small copper heatsinks on the outside of the aluminum heatspreader.

Speaking of which, anyone try MaxSinks? Looking at my Kingston memory the stock heat spreader is removable. In theory one could get just about any memory, remove the default spreader, and put on a MaxSink.

These look very much like the original heatsinks Abulia, but by the time you add the price of a set to the cheaper ( Kingston/Samsung) types of memory, they will add up to the same price as the Crucial/Apple sticks.
Lets hope that the price of these or the memory falls quickly to give us more buying options.

Nice find, Abulia!

As you know I'm trying the route with the little attachable heatsinks onto the stock heatspreader from Kingston. But the MaxSinks look very good, and for $84.99 for a pair, that's still cheaper than Apple/Crucial/OWC ram if added to Kingstons.

I will keep monitoring my heat levels / errors on my kingstons. If I start experiencing anything, then 1) I will post here and let everyone know. and 2) will try these MaxSinks.

THanks!

Wow talk about price gouging on those heatsinks.
Ram is going up a bit as well. Kingston 1gb FB-dimm from Newegg was $180.99 when I purchased. Now at $197.99

Interesting that the pricing for the MaxSink heatsinks, if added to the Kingstons, come up to just a little under $499, the current price for Apple/Crucial/OWC ram w/larger heatsinks.

I think these companies know that our choices are limited when it comes to FB-DIMM upgrades. :mad:

Currently, I don't think generic RAM + MaxSinks are a cost-saving option. Once RAM prices hopefully drop and have met supply, we'll hopefully have more options?

FB-DIMMs aren't going to be a commodity item any time soon (or ever, if Intel's moving to a different RAM platform in 2008). DDR2 (and other types before it) dropped in price because of demand from large segments of the computer population speeding production.

That demand doesn't exist for FB-DIMMs - it's Mac Pros and high-end servers.
