Can't rely on the IFX-14 compatibility chart ... at least in regard to their listing of the Gigabyte 965P-DS3. Doesn't seem "okay" with the number of issues Petra mentioned.
While that may be the case, then I would be testing a "modified" heatsink against unmodified heatsinks and it would no longer provide as as close a representation of what the average user can expect out of the box (kinda like how lapping some heatsinks may help them perform better but it isn't entirely appropriate to compare unless you're lapping all of them).Quote:

Please continue bashing push-pins, they deserve it!! ;)
Petra ?
and what about the IFX 14 WITHOUT that small, tiny radiator mounted on the backside ? Is it still performance leader? cuz I've seen a review without it and it was worse than TRUE.... Could you Petra confirm it ?
It makes such a tiny difference.
The only reason my review showed it to be better was because when I installed the backside cooler, I also modded the mount for much higher pressure :)
So maybe taking just the heatpipes from HR-05 and putting them inside the OROCHI could help ?:DQuote:

The IFX is alot worse than TRUE.... The only difference is - if I'm correct - lack of that small backside cooler
so... where could be the problem ?:>
Also - what about mounting 3 fans on IFX ? would it give an enormous difference or not?
Unfortunately, that's not something that I was paying any attention to (also note that I didn't test the Orochi with the stock fan).Quote:

The PC60B is not the best breathing case out there by any means. It does have a 12cm front inlet fan and a 12cm inlet in the side door but the exhausts are just 8cm fans on the back and out the blowhole. With the case fans in the stock configuration, the TRUE and IFX had almost identical performance, and different fan configurations on the IFX had little effect. The Zalman 9700 was at most 1C warmer than the TRUE and IFX in the PC60B with the fans set up stock and often the temps were identical. That made me think that the case airflow was masking the performance differences between the HSFs. So I took the front fan and flipped it around to an exhaust, used a Scythe Kama Bay to add another 12cm front exhaust and put in a higher flow side door intake fan. That dropped temps for all HSFs by 3 to 5C under load. With the IFX set up with fans in pull/pull orientation, it outperformed the TRUE by 1-2C and the 9700 by 2-3C.
The above led me to pull the guts of my image server that lived in the Armor. My Armor has two Icages and therefore two 12cm front intake fans. It also has a 12cm rear exhaust, a 9cm rear exhast and a 9cm blowhole fan in addition to the 25cm side door fan. After checking all of the fan cfm specs, I flipped the two front fans around so they would be exhausts, mirroring what I'd done on the PC60B. It worked great. The mobo, GPU, NB and CPU temps all went down by ~5C below the lowest PC60B temps. The gap between the TRUE and the IFX widened but the 9700 got closer to the TRUE. Without the rear IFX HS, the IFX was 1 to 3C cooler than the TRUE and the 9700. With the backside cooler on, the gap was 2 to 3C. Again, I ran the IFX in pull/pull and I think that works well with a side door fan that pumps air into the gap between the two TS towers.
So I yanked the rig back out of the Armor and compared the three HSFs on open bench. If I just used the fans that were on the HSFs, the temps were equal to or 1C higher than those in the Armor with the same ambients. That was surprising but maybe it means that the Armor exhaust fans and the big door fan really add to the HS airflow picture. So I put a four high flow 12cm fans around the CPU HSFs and they brought the open bench temps down to where they beat the Armor results. Still though, the IFX had an ~2C advantage over the TRUE and 9700.
My first comparisons were done on a DFI 3200CFX with a S939 Opteron 185 running at 3GHz. But most were on an Asus Blitz Formula with a Q6700 at 3.4GHz with no water on the NB Fusion block.
@ petra
Thanks :)
what do you think of modern aircooling against watercooling for those that don't overclock and are after silence ?
@Clue69LAnd
what about 3 fans - one pushing, one between the two towers and one pulling ??
If you don't overclock you can go passive with let's say Ninja Copper - it will handle even quad cores but you won't be able to overclock them unless you have good airflow in your case... But as long as you don't want to oc - I'd go aircooling... Even if you'll mount 1 or 2 low cfm fans on a radiator in a warer cooling rig they won't be quieter than the same fans on the aircooling heatsink + in wc there's another source of noise - the pump.Quote:

I'd never use water unless it was really needed, such as for OC'ing. There's too many things that can go wrong with a WC loop. Pure passive cooling for low heat load systems does work and if you can tolerate one or two quiet fans, performance is excellent.Quote:

I'm guessing that the advantage of pull/pull is that both HS towers get cool air on their inlet side. If you use a fan in the middle of the towers, one of them will be working with preheated air. I also tried push/push with the case door fan turned around to exhaust and it didn't work as well.Quote:

Nice review :)
Good coolers...i love my ultra-x anyway :p:
If you aren't really overclocking and are purely after silence, then water cooling just doesn't make sense. Where water cooling shines is in providing a reasonably quiet system that can handle the heat of heavy overclocking.Quote:

Shame it costs so much to ship too the UK as i see you have the Orochi on a great sale price :)
