How would you go about fitting a fan above some memory so it has cooling? I have seen the Corsair Dominator cooler but have no idea how its mounted above the memory. Are they somehow suspended above it, or do they clip onto the memory?

With 2.1v going through my memory it gets more toasty than anything else in my case
 
Those memory coolers generally clip onto the top and bottom of the sticks. You might also be interested in looking at the Antec spot cool fan.
 
So in other words, i need something thats bendy and can fit into a motherboard screw hole. Then just poke the other end through a fan.

Might try it with a bunch of those old pipe cleaners you used to get at school. Then poke through 2 holes on a 60 or 80mm fan
 
This is what i did to my ram - but a fan zip tied to the back of you optical bays is ususally fine

I bought one of those Dominator memory coolers and to be honest a fly suspended above the ram flapping its wings would generate more air flow. It was rubbish, could barely feel anything coming out of it.

The thing is designed to sit a fair way away above your ram, in order to accomodate ram with large fin heatsinks like the corsair dominator ram, but if you have normal ram then there will be a big empty space between the fans on the top of the ram, which given the low cfm of the fans in this cooler leads to almost naff all impacting on the ram. Maybe I had a dud but I doubt it, very disapointed in the air flow it produced.

What I did instead was to make a simple bracket out of a bent piece of metal, glue an 80mm fan to it, and bolted that to the case such that the fan was over the ram. Much better though obviously not as bling.
 
Hasn't it been proven time and again that heatspreaders, let alone more complex cooling do the square root of zilch for memory performance?

It must do something, when i put my hand above my memor, its hotter than putting my hand above a heated frying pan! think ill just try and get a fan over them. Those custom heatsinks do look good though. Is there a way of monitoring memory temperature, other than using a probe

yes but by putting a spreader or a fan on them you are just radiating the heat into your case. Better to improve the airflow and remove hot air (including any radiated by the memory) entirely.

Nope. For one thing they protect ram from static damage when being clumsily handled. The heatsinks on mine definitely get hot, and as the sinks are bigger than the ram chips that's a bigger surface area getting rid of heat, so it can't be a bad thing.

+1 for the cable tie approach. Cable ties are brilliant.
 
Get a fan. Cable tie it near the ram. Rejoice.

I've perched a 120mm fan on top of a graphics card, it's cable tied to a convenient piece of tubing.
 
Aside from the obvious reasons of the 120mm fan being better performing and quieter than that, already having a 120mm fan, and skepticism regarding the mounting system of that one?

Cable ties are also cheaper, tis true.

A 120mm fan cable tied to a passing tube and resting on the gfx card quieter? :D

But you are right it might blow the air around a bit better.

Then again this has blue LEDs so the cooling utility will be on a par ;)

^ wouldnt the fan be better over the radiator in push/pull, instead of over memory?

That would help CPU temps but would do little for memory temps, as it is much better to have air blowing onto the memory rather than trying to exhaust the heat away, especially from as far back as the rear of the case.
 
If you haven't used all your memory slots, I'd get some thin fiberglass sheet, cut it so that it locks into place in the empty memory slots (so make it the same shape as a typical memory module), then add a custom bracket to hold whatever fans you want directly above the memory.
