HAF Stacker 935 + Front Mounted Nepton 240M??

Recommended Posts

Case:  HAF Stacker - the 925 part

Cooler:  Nepton 240M

I plan to install the Nepton 240M in the "front" mount position, with the two drive cages moved to the 915R, but I cannot locate a part number or a source for the  "optional adapter" mentioned in the 935's AIO cooler compatibility chart (http://www.coolermaster.com/product/Detail_aj01/case/P131014000315b4/Overview.html -- at the very bottom of that webpage).  

Does that "optional adapter" exist, or will I need to kludge it?

Thanks, Pim

I called the US support number, and they advised that there is NO adapter for this configuration:

1.  The mention of the adapter at the HAF 935 webpage is an error

2.  The Nepton 240M should install without an adapter

3.  They recommend reversing the airflow by installing the fans to pull air into the case, not exhaust it out, as would happen if the Nepton is installed with the standard fan configuration.

 

I offer the above info in case anyone else wants to mount the Nepton (or Seidon) 240 radiator in that "front" position.

Hi Steve,

 

Thanks for sharing the info. Are you planning to mount a Nepton 240M now? :)

Hi Pim,

 

Once a few more parts arrive, I should be able to start construction. 

 

Before then, I need to ream out the threaded holes (the ones used for mounting two 120mm fans at the front of the case):  I can then install two Noctua PWM fans there, passing the longer screws for the Nepton through those holes, and screwing them into the Nepton for a push/pull setup. 

 

I may need to put some cork sheet as a shim between the Nepton Radiator frame and the inside wall of the case front, and also between the bottom edge of the Nepton and the floor of the 925 case, for stabilizing the assembly, but none of that will be a much work as I had rebuilding my old Thorens Turntable!

Alright! Thanks for the update. Maybe you can post some pictures? :D

The project has worked out well.  I will try to post some jpeg images of the process if anyone wants them, but here are the general results:

 

1.  The best way to remove the screw-threads from the 8 holes at the front of the 925 case is to drill them out.  Remember, I wanted to be able to pass the Nepton's longer attachment bolts through the holes, and the threaded holes were too small for that.

2.  You need a 4mm drill bit.  Use "Cobalt" or carbide bits only.

3.  Use a medium-weight lubricating oil such as "3-in-One Oil" on the drill bit.  USE ONLY A SMALL DROP near the point of the bit, and replenish it every 2 or 3 holes - whenever you detect any binding.  DO NOT attempt to drill out the holes without oil.

4.  Mask everything carefully:  Remember that you are creating a large number of tiny shards of metal.  You might want to wear protective gloves, if you don't like metal splinters.   THE CASE SHOULD BE AS STRIPPED-DOWN AS POSSIBLE to give fewer areas for an errant metal shard to hide.

5.  I also used two small (about 2cm diameter) magnets, which had a roughly 8mm hole in their center, to catch as many of those metal shards as possible.

6.  Preparing the case for drilling takes most of the time.  The actual drilling went very quickly for me.  I then used a Dremel tool with a carbide reamer to finish off the holes.

7.  I then glued small strips of 3/16-inch cork sheet (3/4" x 1/4" will do) to the inside face of the case front, so that they could support the Nepton radiator.  The Nepton's longer bolts were actually about 3/16" too long to make a tight connection, so these cork strips took up that slack.

8.  The 2 external fans are Noctua NF-F12 iPPC 3000 PWM, with bolts passing through their attachment holes, then through the drilled-out holes in the case fascia.

9.  The Nepton's Silencio fans and the Noctua fans are set to pull air into the case (recommended by the Cooler Master tech I spoke with).

10.  You will need patience to get the bolts seated in the radiator, but once that happens everything fits like it was designed that way.

 

Temps for the i7 5820K (stock-clocked, but no throttling) are:

Idle:  25-30 degrees Celsius (22 degrees ambient)

Moderate load: 55C

Peak (so far) 79C - but only for Core-0.  Other cores are typically 5-7 degrees cooler.

 

The Motherboard and SSDs are pretty stable at 25-30C all the time.

 

The Nepton has been very good at bringing peak temps back to idle in 5-10 seconds. 

I'm running all fans with no BIOS restrictions so they can sound a bit loud when the CPU is cranking at tis peak.
