I ordered two of the older 4-in--3 modules made by Coolermaster and they sent me the new ones.  The packing list even says the model number is different than on the box.  Does anyone know the pros and cons of each?  My initial though is i almost want to complain and return them because i wanted to use the external brackets i have existing on my case,  but is there anything else that out weighs it?  Is the material that much better in this one?

 

New one is STB-3T4-E3-GP,  old is STB-3T4-E1-GP

I have several of the old ones. They are excellent and do a good job of stacking and keeping drives cool.

 

However changing a hard drive with them is a bit of a pain and since they have no filters they do become quite dirty.

 

 

I have a couple of the newer ones. The main advantage is that they're more likely to fit in most cases without having to modify the case. The front black plastic bezel is held on with screws and can be removed, making the unit look very similar to the older ones. I'd give one of them a try before trying to get them replaced with the older model.

yup went ahead and put one of them in my case. seems great.  i'm having trouble swapping the fan out with one i have that has a controller knob for.  can't figure out how to mount them as the plastic connectors that came with the stackers dont fit and the screws that came with the fans give too much room.  Might need to pick up some sort of spacers or extra nuts at the store
