<< if you look at the side of the fan casing ther should be little arrows showing airflow and fan direction. Sorry to hear about your temps.🙁 >>


Exactly what I was about to point out. I don't rely on which side of the fan the "label" is on because different manufacturers surely have different practices. However, the arrows on the side of the fan housing should make it pretty clear.

Good luck!
 
I didn't even know they had arrows on them so thanks for pointing that out. I've just swapped everything round yet again. With the label nearest to the CPU it's blowing. What I've done is installed my 60mm Sunon again this time so it's blowing on the CPU. I've put the 80mm fan in the case fan holder so it sucks hot air out of the case - I even remembered to punch out the pastic cover (do I win any prizes? lol).

Now my 'puter sounds like [/i]two aeroplanes as you'd expect and my temps are as follows: 24, 52 (CPU), 36 (only 2 degrees less than it was without the extra fan!). Wow, I'm really glad I went to all that trouble yet again *grumble, moan, grumble*. 🙁
 
How Noise Pollution turns $80 heatsinks into $30 heatsinks

I think this artiicle in a round about way explains why fan adapters do not work.

Take an Oversized sink like the AX7 (20 cubic inches)slow the fan down so it is at an equal noise level and it takes a performance hit of 6C on a 100 W

Now take away 25%-50% heat sink volume and you lose another 3-6C, now you are in the mediocre range of performance- It's a wash

I would bet that if you did a test of swiftech, alpha and AX7 same fan they would all come out on the .34 C/W point @ 38 dBA more or less. A different picture when you use a constant in your testing

It is legitmate to take a large sink and leverage noise reduction with the added performance capacity. Although the glaciator performed as well, but that is pure copper vs. hybrid al/cu.

It makes sense to me that a fan adapter on a smaller sink is not going to give you much, if any bang for da buck.

Just my 2 cents

 
Thanks for the link, interesting article. 🙂

So is watercooling any better? I know it costs a fortune and I've also heard that it can be just as noisy as air cooling because you still need hefty fans to cool the water pump. How much truth is there to this?
