Megahalems to Noctua D15 switch

smonkie · 25 Aug 2015 at 14:36

Hi, guys. I own a Prolimatech Megahalems which is 5 years old and despite it's superb performance I'm looking to switch to Noctua D15. Thing is, it's difficult to find any direct comparison between both, taking account of how Mega old is. From the info I have gathered, I guess 4-5º would be an optimistic gain (with better fan noise).

Any thoughts on that?

Looking at a couple of reviews for each, it seems like a fair assesment

Any reason for the switch? I'd be quite happy with the Mega, unless you're looking to push your overclock further?

That's the reason. I got a 6700K and it's stable at 4700 (even 4800) but temps in stress tests usually reach 80º. I thought maybe with Noctua I would be able to keep the cpu under the feared 80's.

It's possible the D15 will be slightly better but it seems like a bit of a sidegrade to me.

Have you tried giving the megahalems a good clean?

80c isn't too bad, what are the temps like in a real world situation i.e when gaming?

Try giving your Meg a good soak in sink of hot water with automatic dishwasher detergent. Slosh it around some let it soak for while, shosh some more. After 20-30 minutes rinse with clear water and dry in a nice warm place or with hair dryer.

First I've heard that recommended, interesting suggestion

Certainly better than trying to blow it out with air, which will still leave lots of little particles.

I blow out with air compressor most of the time. Canned air just doesn't do the job very well.

A good wash every couple of years in smoke free environments cleans all the film buildup and usually give a couple degrees better cooling. . In smokey environments every year may be needed.

Dishwasher detergent is much stronger than soap for hand washing dishes and does a much better job of removing the grime.

If you have hard water that leaves spots on things when they dry, a final rinse with distilled water solves the problem.
