MPJA August Specials, Incl. 60x15mm fan 39¢, more

[mindless1]

MPJA, new Monthly Email Specials.

In particular the NMB 60x15mm Variable Speed Fan looks good @ 39¢... it's a nice size for older processors, SFF system cooling or some of those older cases that won't accept 80mm fans on the rear, except it may not have the correct (or any) connector-plug. I have no idea how quiet it is at ambient/room temp. but it'd run at 7V if necessary.

Also on special are 6' CAT5 cables, much more... you could spend a day just looking over their inventory to meet the $15? minimum order requirement.

Shipping charges are very reasonable, seem to be actual cost, shown right before final order page. These deals are good for a whole month but some items may sell out before then.

MPJA is a great store, but this add looks a little worse than usual. Looks like they still have Panaflo H1As (not the quiet L1As) for $2.95 if anyone is looking.

Shopping cart is broken... good old Microsoft...

I was thinking this months specials were better than last month... not great but I needed a couple 60mm fans, and at the typical internet price of $3-6 each, MJPA will sell me about a dozen, plus unlike fans of unknown origin, NMB are pretty good.

I placed an order yesterday, the shopping cart worked fine then. When I receive the order if there's anything worth commenting about (like the connector on the NMB fans) I'll update the thread.

Thanks. Will have to order some of the 60mm fans. I found some specs on this model __here__ and __here__ (PDF). Guess I'l' have to order some of the other stuff on sale to get up to $15. 🙂

Received my order today, have more info about the fans:

Connector IS 3-pin, and the wires are in the appropriate positions in the connector for attachment to a motherboard fan header, 3-pin power supply adapter, etc.

Fan RPM is roughly 4100RPM @ 12V @ 25C . Not obnoxiously loud but not anywhere near quiet either. Of course that's subjective, if you have a 5000RPM CPU fan you shouldn't find the sound objectionable in comparision but the main point is that the thermal sensor operates over a narrow range, it would have to be quite cool, below room temp, for the fan to spin at a speed i'd consider conducive to low-noise operation.

If you decided to rip the thermal sensor off of one (like I just did, well actually used a soldering iron but prying it off would work too if you don't want to reattach anything in that location), then the fan will run at roughly 1200RPM @ 12V, and produces a bit of pulsing. It's then pretty quiet but the pulsing makes it slightly louder than other fans would be, running at same RPM. However, it barely puts out any air @ 1200RPM... might be enough airflow for a video card with a good aftermarket low-profile heatsink, but this is a fairly large fan for such an application.

For comparision, this is similar to the typical P3-era heatsink fan, would be fine for such an application but still I would've liked it to be slightly quieter at 12V.
