How are these for case fans ?

Deltas

This is what I was told about the 25mm thick version of this fan when I asked about it eariler this week.

hmm the deltas i posted were the 38mm not the 25mm

75 cfm with 35dbs .. i wanted around 100cfm .. i was thinking sanyo denki
105cfm at 39db .. but some people said on here said they have a HUGE deadspot

I'm actually using one of the low speed 38mm Delta tri-blade fans on an XP-120--it is a nice fan--but, I'd still choose the Sanyo Denki. I haven't heard that they've got a huge dead spot, but even if true, who cares? For a case fan, the most important facet is the total amount of air flow, not airflow directed at a component right next to the fan. Also, it's easy to get the Sanyo Denkis for $3 each in quantity or $6 each as singles, why spend 3-6 times that for the Delta?

How well do the Sanyo Denkis work as CPU fans? I was planing on using one on a XP-120 or a Scythe Ninja.

The Sanyo Denki will work fine as a CPU fan, especially on a Scythe Ninja that can actually run fanless or an XP-120 where the heat-pipes bring most of the heat to the outer fins. All fans have a dead spot, but those heat sinks are designed to make the best use of the available airflow, so....

I know you specified you are looking at the 38mm delta...that is why I specified that I was asking about the 25mm delta. I don't want to read too much into what Sen and Larva said, but what I got from the convo is that the tri-blade is a specialty fan suited for CPU applications. I saw you posted in my thread as well. So, I am sure you read the same posts I read. I think MVC made a better suggestion. The sanyo denkis seem to be a popular choice for case fans.

Delta tri-blade makes a better cpu fan than case fan. Im getting some of these beasty deltas from excesssolutions.com:

At only 4 bucks a fan it is a great deal. Also if you dont want something as powerful, you can browse slower ones.

edit: forgot to mention that they DO NOT have connectors attached. But female header kits can be purchased at sidewindercomputers.com

I have always wondered...do you need any special tools to put a connector onto a bare lead?

A crimping tool helps, but I've made do with needle-nose pliers when one wasn't available. The biggest problem with the 3-pin fan connectors is that they are very tiny and it doesn't take much to tweak them into some shape that won't fit properly into the plug (this is also the case with the ATX pins/plugs). For them, I really do recommend using a proper crimping tool. With the 4-pin Molex connectors, there's a lot of room inside the plug so as long as you don't damage the locking tabs they'll insert fine no matter how badly the "crimp" is mutilated . But, if you don't have a real good crimp, I'd also suggest soldering the wire to the pin just to make sure it stays where it's supposed to. Here's my "wiring" tools, minus the soldering iron:

Ok, thanks. It sounds simple. I have all the tools (my other hobby is car audio ). I had never seen it done or heard it described. So, I always just wondered.
