Today, I improved my modifed D8000 (based on the compucase LX-6A19) to include the new Thermalright XP-120. Now this computer only has 4 fans, all of which are 120mm! Wehooo.

As expected, it sounds even better and my temps dropped a couple of degrees.

Is that a JMC 120 on your XP-120?

What happens if You remove the front 120mm fan? Temp-wise, that is... :)

BTW, Ed: How did You ID that fan? Is it the ridiculously-sized hub?

Cheers,

Jan

KatanaMan,

It’s hard to believe that’s an XP-120 under that fan. Photos I’ve seen of XP-120’s, in very similar (120mm exhaust fan) cases, show the XP-120 (+25mm fan) to be big enough to mask about 30% of the rear exhaust fan. However, yours appears not to mask any of the exhaust fan – or is that an optical illusion of your photos?

Size of the central hub, curve slope of the rounded edges to the central hub, number and position of circular divots on the central hub and finally the shape of the indentations in the fan's frames.

Sooty,
That is because of the mobo used.

Most mobos have (from the back of the mobo to the front):
Back plate/CPU socket/DIMMs/20-pin power connector

This one has:
Back plate/20-pin power connector/CPU socket/DIMMs

So the CPU HSF is located further from the back of the case.

Thanks Tibors, for explaining the MOBO configuration – I didn’t realise that. Are you saying, because the CPU is located further to the front of the MOBO, that this explains the optical illusion?

I’m sure the XP-120 should be sitting way-out into the air-flow of the rear exhaust case fan. Just doing the sums:

XP-120 height 63mm
120mm heatsink fan thickness 25mm
120mm rear exhaust case fan 120mm diameter.

This adds up to 208mm, and the D8000 case is 210mm wide. However, I haven’t included in my sums thickness of: MOBO and CPU, MOBO stand-offs, MOBO tray, gap between MOBO tray and L/H/S external panel, L/H/S external side panel, R/H/S external side panel. This all adds up to way more than 210mm. I’m sure the XP-120 with a 25mm thick fan would be pretruding 30-40mm into the air path of a the D8000's 120mm case fan.

That’s my only reservation with the XP-120/90, there’s potential conflict with the rear exhaust fan. But if it doesn’t extend that far, then I've no reservations.

The XP-120 mounted on a removable MOBO tray.

Image

Notice how the height of the XP-120’s fan, is almost level in height with the end of the PCI slots. On the D8000, that would extend the XP-120 about 40% the way across the 120mm case fan.

Edit: I think that’s a 38mm fan they’re using in that photo. Still a 25mm fan, might be closer to 30% across – my original estimate. The XP-120 is massive, but if Katana’s photos are anything to go by, and it doesn’t extend into the case fans ‘air space’ – that’s great news, I’m just very surprised :lol: Katana’s XP-120 fan, doesn’t appear to extend higher than the MOBO back-plate, let alone the PCI slots. :?

Hmm, I thought we discussed this in some other thread, maybe an XP-120 thread?

Well, in case I haven't posted this pic before, here it is. This is the XP-120 +120mm Globe fan setup in my 3700BQE:
Image

Yes, the CPU fan does overlap the rear case fan by around .75" (but keep in mind, this particular angle makes it look worse than it is, kind of the opposite of Katana Man's pics :) ).

Note that I have the CPU fan in a "sucking" orientation. Not only does this cool the CPU better (see the charts in my XP-120 review) but I figure that it also helps the rear case fan suck out the warm CPU air that's being thrown up in front of it.

My motherboard is an Aopen AK-86L. (I personally feel Aopen is better than Asus lately). In most systems, the heat pipes of the XP-120 are toward the ram side. On my setup, the heat pipes are toward the back plate. This moves the fan toward the front of the case giving plenty of room for all fans to work nicely. Of course due to the size of the XP-120 heatsink, orientation will be limited to the spacing available on each motherboard.

On the other hand, even if the fans are cramped a bit, and even if there was some turbulance, I believe the 120mm fans are still the best way to go.

Have you considered just ducting the sucked air off the XP-120 out of the case? That way you could consider removing your rear 120 case fan.

Thanks Ralph and Katana Man.

The XP-90 is 12mm taller, btw, so that has more potential to cause problems.

In cases where there might be conflict, with either XP cooler, perhaps mounting the exhaust case fan on the outside of the case (instead of inside), might lessen potential conflict??

Sounds good to me IF you have your PC located/positioned where no fingers or pets can reach - like mine. (Call me lazy, but it is quite a headache to get the PC in and out of the cubby hole, especially when the PC has rubber feet pressing against a wooden panel so that it doesn't 'slide' out.)

Katana, what PSU is that (what model) and what are your opinions about it? Did you made a fan swap?

It's a Fortron FSP350-PN. Sparkle is a subsidiary of Fortron. If you find the Sparkle version (like here from newegg) they are the same thing. They rock. They were the first to come up with the 120mm fan idea. I've noticed that Fortron will often sell their porducts to companies like Antec who will re-badge them. So you may find the same hardware in other company's PSU's. There's no reason to change out the fan, it runs at a very low voltage 99% of the time. Probably somewhere in the 5V-6V range. There's a good thread on this PSU here.

The Sparkle 300W model, has 18amps on the 12v line. The Fortron 300W, has 15 amps...So...? :?: :roll:

Does your PSU gets hot or very warm to the touch?

No, it does not get hot. Feel free to continue this discussion about PSU's here.

That's what I've been thinking of. I have a bunch of Panaflo 120mm fans.
