Generally, cpu fans sit flush to fins in order to apply the static pressure required to push air through them.

The fins are also generally further apart.

The flaw, which i've just realised is that the Curve inwards on the side of the heatsink prevents a single fan from applying enough static pressure to push air through the fins. This is generally not a problem for a push-pull setup, but for those who lack the room to apply this will inevitable hit this.

I would have a feeling that the designers knew this fact, which is why they created the plastic mounting clip which the wing across the top and bottom seals the gap to allow more static pressure.

Notice where the plastic clip covers.

Sorry for posting a bit late, I've been gone for a few weeks and playing thread catchup .

I ran my TRUE with a single fan in push config for a little while after building my i7, and while I noticed the same issue, it didn't seem to affect it too much. I now have two fans in push-pull and temps decreased marginally. Both fans on it are about 1300 RPM so they don't move a whole lot of air. Here's a picture of the initial single-fan setup and here's the current dual-fan setup.

haha, that elastic? around the fans would work to attach a 12mm deep fan on the reverse side of my TRUE

Yep, just 4 zip ties cinched together. I put the second fan on sometime early this year (February?), and it hasn't moved at all. I was originally going to get a second set of the wire clips that come with the heatsink, but everywhere I looked it was out of stock, and some website suggested the zip ties.

The fan seems to sit snuggly enough in the grooves of the heatsink that it wouldn't move even without the clips

One of the sides of the heatsink has those little silicone strips along the edge to grip the fan, I can't remember if the other side has them too. But yeah, the zip ties are on pretty tight so the fans don't move or vibrate at all .

Are those pics from your setup? How many times are you gonna disassemble/reassemble it already? :lol:

 

[Squall-Leonhart]

nah, just pics from the webz.

Well i bought a Bufallo and it only has 1 fan.
If i put another fan on the back, my temps would probably decrease right?

I didn't had time to place it on my pc, will probably do that next week after uni exams.
