in case XP-120 wouldnt fit on future NF4 Gigabyte board...

[flexy]

XP-90 ?

really, really would like the XP-120 since i designed my whole system basically around overclockability.
Which one would be the next one below the XP-120 in case the XP-120 would not fit the motherboard ?

Probaly an XP-90 would be second. I would also recommend a Zalman CNPS7000 or 7700 as they are very quiet and are very effective too.

I don't dispute that, ComputerMAn, under available information.

Here are some questions that need answering. I can provide a few answers, but only as observations, assumptions and caveats.

"Does the XP90 cool as well as the XP120?" I think it may, if the user pays attentiion to "equivalent fan throughput". I also think it has the same surface-area in aluminum fins, but someone might want to check that point. And I am making an assumption that the same heatsink base, same heatpipes and equivalent fin-surface-area provides the same cooling.

Second:

"Does an XP120 cool better than a Zalman CNPS-7700-Cu? (Or for that matter, the CNPS-7000's)"

This just in:

Tweakers 4U Deutsche magazin, auto-translated comparison review

Do not trouble yourself so much at making sense of the auto-translation, meine Damen und meine Herrn. Sehen Sie die Bilder -- die Nummer. Look at the graph and the numbers.

I can only infer that the XP90 is "the best" under the assumption of cooling equivalence above. Still, it makes sense to me. But -- please -- at least try and select a 92mm fan with 70 to 74 CFM. Well -- 60 then. Just my preference . . . .

PS

Suggested low-noise solution to bring high-throughput CFMs to top of an XP90:

Purchase:

Zalman fan bracket

Bracket

Acrylic 120-to-92mm fan adapter

Adapter

Scavenge:

used 92mm fans -- probably two of them

Acquire:

cable ties, some superglue or silicone adhesive

Solution:

Cut the guts out of the two used fans. Use glue and cable-ties to mate the remaining fan-frames; trim off excess cable-ties. Use self-threading screws to attach to frames to the 92mm side of the Acrylic fan adapter. Secure the adapter and 120mm fan to the Zalman Bracket, attach the Zalman bracket to the PCI-slot-screws on the case rear, adjust screws and fan/adapter/duct position. Dremel off some of the 92mm-fan-shroud duct until the assembly just touches the top of the XP90. Seal any cracks or seams with silly-cone adhesive sealant.

GREAT PRICE ON THAT FAN-ADAPTER TODAY AT NEWEGG!! You get the fan thrown into the bargain -- not bad.

Pros: No weight added to the XP90. More CFM with less noise . . . . I'd say a lot more with less noise.

Cons: Less than $20 and your time. Slightly reduced fan throughput for the 120mm fan, (but minor loss compared to gains).

hi,

if i'd go with the xp-90 and get
http://www.svc.com/en92vasphipe.html

is this a good fan ? the cfm and dba looks quite good to me and i like the fact i can adjust the speed.
(Noise is somewhat an issue for me)

Other recommendetations ? (good airflow and moderate/low noise)

I dont want the ZalMan cu flower since i heard it might not be optimal for overclocking, otherwise it is certainly a nice HSF.

edit: "recommendetations"...LOL

i also like the idea with a fan adapter, eg. this bracket looks interesting.

can i just get this bracket and mount a single 120mm fan over the XP-90 with it ?

BD: ok, after reading a few times i think i now got what you meant up there 🙂

You could do that, but in consideration of how your choice of heatsinks is designed, you want two things to happen: you want the airpressure at the heatsink fins to be at maximum, and you want to force all the air through those fins. So the 92mm duct idea has a purpose. That includes both the adapter and the duct. The adapter has aerodynamic properties that minimize the resistance to the fan of forcing air through a smaller hole; the duct keeps the pressure constant and forces the air through the heatpipe fins.

The heatsink and pipes will perform better if you can make the fan's throughput feed exclusively through the cooler before going anywhere else.

As to the Enermax, this is the same design and manufacturer as for the 120mm fan with the same features. I said in other posts that I went through two of them, discovered something funny about the fan monitoring capability, and that if the fan was rated at 2,600 rpms, I couldn't get it to go faster than 2,200 to 2,250 on either of three different computers with PSUs in the 480W to 500W range. Nothing wrong with the test-beds -- all other fans worked according to spec. The 120mm job drew 0.30 amps @ 12V. I've had Sunons which were just as quiet, ran at that amperage, and seemed to meet their specs.

You take your chances. But maybe you'll like the 92mm Enermax. I just think there are better choices.
