PWM 'Daisy chaining' - Page 2

post #11 of 20
Pretty sure 150cfm overshadows proper airflow. Why? With that kind of flow, a mid-tower will go through at least a dozen air changes a minute. Not many places heat can hide for very long in such a confined area, with that maelstrom of air.

You're thinking with your wimpy little low speed/pressure fans. My fan will propel itself, and 3 others, across a desk. tongue.gif

since that rate of airflow far outsurpasses the rate heat is displaced by the component cooling, all its doing is making a bunch of noise for no reason.

I'm trying to avoid high rpm fans tbh. They're not really needed for my uses. Absolute silence isn't required, though I do have a certain threshold that won't be crossed for the sake of slightly lower temps smile.gif

I've got past my pwm 'blonde moment' and have had a little look into airflow. Now I'm probably going to shoot for a Zalman flex cooler (because it's only £27 and I uh, like the way it looks redface.gif) paired with a couple of Thermalright TY-141's. Yes, there are slightly better coolers around, but I can't really justify the extra cost for the sake of a few irrelevant degrees of difference.

I'll also be putting two more TY-141's on the front intakes, and for budget reasons (£4.39 each!) I'll be using 3 Arctic F12 PWM (not pro's) at the Rear exhaust / Front top intake / Bottom intake. The Arctics are certainly not the greatest, but they really aren't bad at all - especially for the price. The standard versions also put out a little more air than the Pro's and are way more versatile with mounting options due to having normal frames. They can always be upgraded later on.

Anyway, that's the initial plan, but I'll be experimenting with fan positions + positive/negative/neutral pressure etc, so stay tuned!

PS, if anyone has any alternative fan recommendations, I'm all ears until monday night tongue.gif

PPS, I've seen conflicting info regarding having a rear exhaust fan when using a push/pull cpu cooler. I don't know why you wouldn't, so perhaps someone can enlighten me?

What makes you think you are really gettng 150cfm airflow? Did you measure how much air is actually coming out of your case?

You need to consider how much resistance your vent grills, filters, HDD rack, etc are decreasing the 150cfm.... and just because you change the air in the case several times a minute does NOT mean there are no hot spots where air is not changing. wink.gif

If youve seen how crOwded my case is, then youll immediately see a reason For such a fan. Heat generation? I have a 3770k and 2x7970s. Proper airflow? Pretty sure my design is better than yours, especially at low speed.

Your design is probably much better then mine. Can we have some pics and details so I can make mine as good as yours please?

The 3 intake feed directly to the cards which exhaust their hot air outside of the case. No turbulence created by a *ahem* fansink, which also tend to recycle PSU air via vented PCI slots.

Simple, clean and effective. No convoluted attempt to use a heatsink that weighs over a kilogram, unnecessary justifications with laws of thermodynamics or need for fans that just don't look right. Plus, its extremely hard to get any component to even momentarily kiss 80c, which is well below their rated TJ Max.

Very nice indeed.

But my 1.3kg cooler with fans is lighter and takes up less total space than your radiator, fans, pump, reservoir and heatsink... not to mention all those hoses getting in the way of components. biggrin.gif

As for hot air heating up case... well... my sinkfan exhaust is ducted directly out of case so not an issue. biggrin.gif

Seriously you have a very nice rig.

I was trying to point out the 1KG weighing on the motherboard lol

Thanks for the compliments smile.gif
