If you have to undervolt Deltas, they're pointless. Delta fans by design run very fast, but are extremely inefficient at low speeds. A fan with a lower maximum rating would be up to twice as powerful for the same noise level. Go for high-speed versions of trusted fans like the Scythe Slipstream. I use six of the 1900 Slipstreams as you have linked, and they're excellent - very powerful at high speed, very quiet at low speed.

Ah hah! I finally plugged mine in last night. It was bearable at full speed! And was pushing quite a bit of air. Can't wait to compare it to the Tuniq's stock fan. While I'm sure the comparisons been done, I'd like to see it for myself :p
WITHOUT running wires through the fans thank you very much ROFL!

A much more reasonable 68 cfm. There's no reason to ever need that powerful a 120mm. If you need that fan to keep your computer cool you have something seriously wrong with your cooling scheme! At 37 dBA, it's also very loud. Remember too that if you are using it as an exhaust fan, you have to have enough intake airflow to balance that fan's output airflow. Otherwise it runs hotter because of high negative case pressure. I'm going to increase my intake air by 15 cfm, by moving a 53 cfm Silverstone fan from the rear, to the front as an intake. The fan I just linked you is going in the rear, as an exhaust. Both fans are about 15-17 cfm higher than the fans they are replacing, so the balance of the case airflow stays about the same. A lowering of the side 80mm Silverstone exhaust fan to about 800 rpm should be just about right!
Best Regards,
Russ
Thanks for the advice Russ. Since they're going to be on a fan controller they will be running only as fast as needed so there's no real need to buy the 1200 rpm one's instead of 1900rpm to cut noise. Also the 1900 rpm one's will be ~7$ cheaper lol.

Oh well it was worth a try, never know when you might need a 240cfm fan lol.

Never. I agree with Russ, if you need that much airflow all the time, you're doing something wrong!

Going off balancing the airflow, anyone know of any high (above 68cfm) cfm 140mm fans? My case has 3x120mm intake fans (front), 1x120mm exhaust fan (rear), 2x140mm exhaust fan (top).
The other option (besides better case fans) would be to place a slot cooler below the chipset; even though I'm not a fan of those that might be the best solution.
I forgot to take a picture when installing the new gpu so this will have to do:
The black square indicates the approximate size of the cpu cooler and it's top barely clears the side panel. Red arrows indicate fans and their airflow direction.
Any advice is appreciated.
TIA,
redmaw

personally i think haveing more of an intake is better than an output. that way air is forces though the back slots/mesh etc, cooling differnt parts of the case.

Thanks shaffaaf, that could work, didn't even think of it. It would force some air past the chipset which is in a dead-zone right now. Usually I go with a negative air pressure design although I don't think I've ever seen any benefit lol.

I usually use negative pressure, but for the moment I think pressure is slightly positive, simply due to the way my case is laid out. Personally I think as long as you're close to being balanced, it doesn't really matter which way round you have it, but it should be noted that due to the way fans mount, intake fans are always noisier than exhaust fans.

russ & sam, if 1/2 of a dual core craps out, would it still run & if still able to run, would it showup up as a dual core or as a single core in windows?

It would still show up with its model number and stepping, though I'm not sure if it would show the second core. I imagine it would work much the same as unlocking the extra core on the Phenom II X3, but in reverse.
It would also depend on what caused one of the cores to fail to begin with. If a core just up an died, I'm sure it would run much like many other CPUs with disabled cores do. If there were more damage than just a faulty core, you might be hard-pressed to even get it to work...

customer's compaq is a dual core 1.6ghz with 4gig ram but showing less then 3.25 gig because vista 32bit. just finished do a system recovery but still as slow as before & not good at all for multitasking as it will almost freeze. seems to me as running as a single core 1.6ghz. the problem seems to happened about a year ago as i'm told.

I'd almost tell you to try using Killdisk and do a complete reformat. AFAIK system recovery only restores missing or damaged windows files. It doesn't clean out junk and clear driver errors. That's more the territory of third party apps like Driver Sweeper Pro and CCleaner.
Ctrl+Alt-Del and on the performance tab it will show all available cores. If the core wasn't working properly, I don't think it would even start up unless there were a way to isolate or lock the core. So if task manager shows the core and that it is being used in any way, I highly doubt the core is faulty.
Also don't forget Vista is a huge system hog and almost any system can be noticeably slugged down by it. Using the 64 bit version with at least 4GB of RAM is the only way to get semi-decent performance. A 1.6GHz dual core would be hard pressed to really push Vista smoothly to begin with, let alone with a couple years worth of small errors and junk files caked on top of that.
In Task Manager how many processes does it show open for all users? These add up quickly and most people don't even notice until the machine is bogged down so badly it doesn't work properly.

ddp,
I've only seen that happen once with an Intel, a Q8400. It showed as a Q8400, but only had two working cores. It could also show as a dual core, depending on the bios version installed.. With the Q8400, something happened with the connection between the two die's, where only one worked. I imagine that would wreck havoc as far as the L2 cache goes. I don't imagine that happens very often.
Best Regards,
Russ

Yeah then I'm stumped. It could simply be a failed core. But that also depends what shows up. Does CPU-Z say 1 core or 2?

don't know as i didn't notice the 2 cpu screens in task manager. i might have to go back either tomorrow or friday if they still have a problem with a hp printer that does not have vista driver. shows up alright but won't print. might give them a call tomorrow to have them do task manager to see if shows 2 cpus or 1. task manger on my xp pro only shows 1 cpu screen but would show 2 if i had vista/win7 on it as i have a dual core 2ghz.

I have XP Pro, and it shows both cores. Select the "Performance" tab at the top of the screen, and it should show 2 graphs.

Well, if you need a 2TB drive to be fast, the F3 is about the only option. I'm still a bit wary of big Samsung drives after the F1 debacle.

Could B over though SAMMY
Samsung is usually pretty good about fixin their Problems
The revues look really good at newegg, they do only go back as far as 12-24-09. So really that's only 3 1/2 Mons
I Might get Lucky, and Russ will call Samsung, About previous Mishaps with their larger drives. See if they did do something Significantly Different 2 improve their larger Drives
I really think all the large HDDs have had their fair share of problems
I've been real happy with my WD Blacks
So far I've had no problem with the WD Blue
I think I might give Samsung 2T a try
I really like their 500Gig drives, even over WDs
