Clearance

257mm (reservoir bracket installed)

277mm (reservoir bracket installed w/o cover)

350mm (no reservoir bracket)

390mm (HDD cages in front position)

515mm (no HDD cages)

** Phanteks released a Revised reservoir bracket to accommodate dual GPU configurations easier and without modification to the bracket. This change happened sometime in Q4 2015.

** For more text measurements you can also refer to the 1st post of the Phanteks Case Club FAQ here. **

Picture Measurements:
- Alphacool UT60 and XT45 Measurements in Push/Pull orientation, with 24mm and 38mm fans (bottom of case only)
- Also included some measurements and visuals of XT45 in top position of case, with/without fans.

Disclaimer: These may be off a few millimeter due to holding the tape at a very slight angle in some cases, or due to optical illusion from camera angle, but for the most part they should be useful as reference or within 1-3mm actual.

Another Disclaimer

the hanging drive cage that I measured up to was unsupported at the time, and naturally sags probably 2-3 mm at the very end of it, (farthest point from front) so you may have to take that into account with the measurements up to the drive cage.

I can take some other measurements right now by request, since my case is all apart and it's easy. Once I get it all assembled it may be harder/impossible

Enjoy

Does the 480 still fit in the case bottom if you leave the lower section of of ODD panel in place? I see you have cut yours so it shows the entire length of the 480m rad.

Thanks

Actually I didn't cut mine, the entire section is removable with regular screws. I just removed it for construction/modding. The Alphacool rads up to 480 will fit width wise while keeping the whole side cover in tact.

How wide of a radiator will fit in the top and bottom? I tried reading the pics but the rotations are throwing me off.

420 up top if you remove the drive cage and its supporting panel. same on bottom. Generally any radiator larger then a 140.2 will require removal of the entire drive cage area. 120mm sized rads however do not.

I meant width not length. I was going to put a 480 in the top but need to know how wide a radiator will fit, there's plenty of info for length but I haven't found width.

480 is a 120.4 radiator, so 120mm + a few mm

I'm pretty sure the top has more clearance than the bottom as far as width. Bottom width with the 5.25" side panel is at least 124mm clearance. You can fit Alphacool series radiators in bottom with no clearance issue. It can be tight if you run a Monsta radiator, since the grommet on the side will bump the radiator over 2-3mm and you may actually have to remove the grommet to fit that side panel back on.

I can probably take a top measurement and post tomorrow.

I found some bottom measurements and posted them under General, looks like maximum bottom rad clearance is roughly 126-127mm judging by the picture.

Edit: I thought I had a picture measuring the width of the optical bay, that is the width that will determine radiator support. I measured it out at 145mm so at least some models of 420 radiator will fit up there and slide all the way to front if needed.

It is worth noting that the bottom of the Primo case is NOT fully vented.

There is a sold section that blocks airflow for a 120.3 or bigger radiator - (BAD design - IMO). The factory makes a depression that is solid for the front foot of the small mount it comes with that can hold two 140 fans and is removable - thumb screws. This solid section will block 30% or so of the third 120 fan.

My Alphacool XT45 - 120.3 is a tight squeeze in the bottom; (side to side) due to the rubber grommets and 124.5 mm rad width on the housing of my rads.

So, either you drill a bunch of holes into the bottom of the case, custom make a frame to raise the bottom rad to allow room or purchase a shroud to give room to breath.

For a case advertised as taking large radiators on the bottom - I found this design oversight to be very frustrating. [come on Phanteks: either perforate the whole bottom or include a bottom stand for 120.3 or bigger rads.]

My Alphacool XT-45 120.3 fit in the top very easy, push/pull with 25mm fans. I placed the top fans above the case mount, rad against case from underneath, then bottom fans mounted to rad. -top grill fits just fine.

That is true, my case was modded for these pictures and I cut out the whole 480 length of the bottom of the case and installed a custom grill. The stock case bottom definitely has some restriction there, lots of honeycomb across the bottom but there is that one section that is solidly blocked, annoying for sure if you are using a large radiator.

I found a pic before I took it to the dremel, showing the support structure at the bottom.

Hi! I've got a 269mm long graphics card (msi gtx 970) and would like to know how wide reservoir i would be able to fit on the res bracket between the motherboard and 3.5 inch drive cages? What is the highest diameter?

That's roughtly the same size as my r9 290s, with that in mind look at the first post under General Measurements, click that Spoiler and expand you will see a lot of pictures with measurements.

Pay especial attention to the 6th image from top, it measures from the 5.25" optical drive bay - out. There is a little lip there that a reservoir will hit before hitting the drive cages, you can see that in the picture #5 directly above it where it is measured off the drive cage itself.

I would say you have about 72-73mm clearance

My EVGA Titan-X SC are 266.7mm long per the spec. sheet

I moved the hard drive cage to the forward position and use the EK-RES X3 250 reservoir (60mm Dia.Tube) on the res. bracket. There is still some room left between the back/ bottom of the 5.25 inch external drive bay. I still have about 14mm of space left to center the acrylic tube in-between.

How long and how wide of a radiator can you fit on the bottom radiator bracket? I know it's meant for 280 mm, but I want to know so I don't buy a radiator that has a shroud that won't fit. And is a push/pull setup with a rad 60 mm thick enough to start interfering with the top grommet?

You should be able to determine your answers by expanding the pics above. Looks to me like there is over 300mm length in the bottom and 145mm width. The last 2 pics in General show the width, a 140mm fan just barely fits it looks like.

Look at the UT60 push/pull with 24mm pictures, the top fan will just barely touch the bottom of the grommet, and if you are using a wide radiator you will likely have to just remove that grommet, which is really easy to do.
