Cooler RAM equals cooler CPU ?

So I just got some Arctic Cooling RC modules for my Vengeance memory and oddly enough my CPU temps have dropped by 6'c, shows you just how bad the stock heat sinks actually are.

Highly recommend these, they look awesome to boot -

For a start those RAM heatsinks will get in the way for many people who have large CPU heatsinks. I can't see how cooling the RAM has cooled your CPU by 6 degrees unless your RAM was that hot it was heating up the entire surrounding area.

Cooling the RAM better doesn't help. Cooler running RAM i.e. RAM that uses less electricity would help lower temperatures inside the case.

Adding sinks does nothing for the CPU as the internal flow is the same as before (potentially worse) whilst the RAM is using the same amount of watts as before.

Not sure if serious...

They look large enough that they could be altering the airflow in your case which could explain the drop in temps.

Oh your totally right I made this up just for a quick laugh.......

This does seem to be more of a realistic theory.

I am quite baffled though as to how adding heat sinks to ram lowers the cpu temp, maybe an error in the monitoring software ?

Is this idle temps?

There are many factors so it might be partly coincidence? e.g. ambient temperatures

The airflow seems most likely, however I would have thought they'd block airflow rather than somehow improve it!

Yes it is idle temps, temps are now hovering around 29-32'c.

I'd imagine, the only way a change in your RAM configuration could affect CPU temps, would be if you lowered the RAM voltage. This would put less strain on the chips memory controller and potentially account for a lower temp.

Either that or a change in airflow around your CPU, or a cooler ambient temp when you measured.

Not trying to discredit you at all, but I'd say you knocking a bit of dust off one of your fans while working in the case, would be a more likely explanation for the lower temps
