I know the logical places to put them but which one's go where, ie: front intake fan sensor on cpu or graphics card? Also I'm not sold on buying/replacing the rear fans. I like the idea that they are plugged in to the mobo, what do I lose/gain I if don't do that change, besides the lower cfm with stock fans?

I know the logical places to put them but which one's go where, ie: front intake fan sensor on cpu or graphics card? If your going to use the temp sensor for the Tt SmartFan, Id say the Graphics card due to the length of the Sensor's Wire...... or Use the Rheobus Switch that Comes with it and manually control the fan. Mount the New Tt Smartfan like in Stage 1. Use wireties if you have the "newer" chassis like Bubba's. (See Photography) ----------------------------------------------------------------------- IAlso I'm not sold on buying/replacing the rear fans. I like the idea that they are plugged in to the mobo, what do I lose/gain I if don't do that change, besides the lower cfm with stock fans? The Stage 2 Mod(rear fan replacement) is as Important as Stage 1 and 3 to maximize cooling efficiency. I personally felt it was the missing piece to the Push : Pull Effect for Proper PC cooling. The 92mm Stock Nidecs' thermistor's are designed to control Noise, not Temps. The difference's in PSU power vs. Mobo can be many... If you dont power your Fans on the Mobo...... 1.Fan Failure Error Logged in Bios at Boot: Solution: Press F1 to Boot. No big deal. Just clear your Bios Log warnings every couple days/weeks if you power on/off. 2. Mobo will last longer due to the EXTREME power that these fans are capable of inducing. Ever heard the XPS sound like a Hairdryer at restart or boot up? How long before the mobo is fried? Solution: Guarantee Prolonged life of your mobo, dont power ANY High CFM capable fans, and the Factory Rear Fans are HIGH CFM when there Maxed. Its a safety precaution. ----------------------------------------------------------------------- Just like in Need For Speed Underground....You can't have a Stage 3 without a Stage 2, and also a Stage 1. Heatsink Fan is a Must even if it's 32CFM rated. More info to come from other user's.... T.RoW |

My fans are wired this way; 2 rear exhaust fans with +- leads wired together, powered by the PSU. My CPU fan (Thermaltake 90mm Blue UV UFO Fan) is also powered by the PSU. Both the rear exhaust fans and the CPU fan have the RPM signal wire going to the appropriate connections on the motherboard. When I boot I never get a fan error for the rear fans it's always for the "front" fan (my CPU fan) and it's not all the time. I'd say 50/50 is an accurate estimate of how often I get this error. I have tried tickling the sensor with different fan speeds to no avail... Is there a magic RPM that I need during POST so I can fool the BIOS or is it a voltage issue with the CPU fan that is so different than the stock Dell front fan that the Bios can tell the difference? |

I powered my "Thermistor Override" mod'd fan(92mm Nidec) improvised as a Slot Card Fan.....from the F. Fan Connector on the Mobo. The 92mm Nidec was running Maxed out because I connected the thermistor "prongs" together with a piece of Wire(Thermsitor override mod).
I didn't notice ANY problems until I ran a benchmark test on 3Dmark03.
The System speaker made a Solid, Non Stop Alarm Sound, So I powered down and Removed the Thermistor Override Fan which was mod'd to a PCI Slot Blower Slot so I could secure it to the slots, as if it were a Slot Fan Card...(Pic would be so much easier to describe)
+++++++++++++++++++++++++++++++++++++++
The F. Fan Connector on the mobo Does Detect Fan Speed on MBmonitor. Which means I could probably Power my 32CFM 80mm Blue Led HDD Cage From it with no problems...Being there about the same specs as the NMB stock F.Fan.
The F. Fan connector is most likely guardbanded to detect voltage/wattage and possibly RPM's in case the fan fails, or Rises Above a certain RPM level. This is hypothetical for I didn't Test the hypotesis of voltage/wattage.
I only could confirm the F. Fan Connector Reading RPMs From MBMonitor.

Yeah I would really love to know how you set the 92mm nidecs up as slot blowers, I think it is an excellent idea for the GPU. Did you notice any difference when overclocking your gpu chip or memory? Picts. would rule.

Ill post a pic this weekend, its 'different' to say the least....All using Cable Ties, and a PCI SLot Blower Slot Cover Piece.....

To clear the System Event Log: (aka Fan Failure Error Log)
1.Go into BIOS at Boot, Press F2 When Prompted.
Scroll down to System Event Log(Press Enter)
Highlight Clear System Event Log(Press Enter)
and/or(not at all if you wish)
Mark ALL Entries As Read-(Optional)

I understand that the rear fan mod can not be done if they are plugged in to the mobo because of hi rpm's. Is this correct? Is there any scenario that would allow this with no system errors or alarms? I'm thinking of fans that are rated the same as stock but no thermisters like stock. What would be the max/min cfm for the rear fans? I like the idea of buying 92mm smart fans so that I can use the sensors to alter the rpm's automatically. Could they be plugged in to the mobo safely if I used the stock connectors?
Is my confusion evident? lol

You could allways try to figure out where to implement the stock fans in your modded system, maybe a graphics card cooler. Use your imagination.

Could they be plugged in to the mobo safely if I used the stock connectors? For the Rear Fans: You could Use lower CFM fans, anything rated at 50CFM or below and power them from the Mobo using the connectors. **Not powering Higher CFM fans from the mobo is a precaution, especially with the XPS's guardbands that detect max/min fan speeds, yet alone wattage/amp ranges.(In theory) Dubbabubba discovered that it's a 50/50 chance on Fan Failure logs at Boot up, meaning sometimes you get them, sometimes you don't.Press F1 and You don't have to worry about it, Just clear the Log in the Bios every couple days/weeks. Your going to find that due to Dell's proprietary setup that these 'issues' are inevitable. But there may be a aftermarket fan out there that in fact solves this(fan failure Log) problem, and it has yet to be discovered. T.RoW |

Thanks all. I have fewer questions now. I recv'd my hardware today(zalman alcu cpu cooler, T/t blue led smart fan.) Got everything in ok. Except my cordless mouse wouldn't work! Took 45 min of screwing with it but all's well again. Case and cpu temps are down by about 4 deg. Btw I put the smart fan sensor on the Ram. Any thoughts on that? So where does the yellow wire from the fan go? With a cooler on the vga and the rear fan mod they can go lower. Hope fully pics to follow.
Before mods at idle
Case 39
CPU 41
Harddrive 37 deg C
Case 30 deg C
CPU 33 deg C
Harddrive 32 deg C

With a cooler on the vga and the rear fan mod they can go lower. Hope fully pics to follow. Before mods at idle Case 39 CPU 41 After mods 35 38 The yellow wire is a Tachometer wire to monitor fan speed. I cut mine off (but wish I would have tried to see if the Mobo Fan Connector would recognize/read the Fan speed w/out the Red+, and Black- Wires of the original Stock Fan installed.) ***If you decide to do this Double and Triple Check your using the Correct Tach Mobo Pin of the 3pin Connector! ! ! ====================================== What are your ambient temps?(Room Temps) Where did you place the Intake Fan? Did you use ArticSilver Ceramique or ASilver 5 on the CPU? ======================================= The RAM Modules probably aren't the optimal placement for a Temp diode, but if the Smartfan's RPM's Max out under load...Your Good. I would use the Rheobus that came with the Tt Smartfan to get an idea of Fan Speed/Sound to get an idea if the Fan's setup right. ======================================= Pics would be great, let us know...more to come.

Thats what I thought the Y/wire was for thanks. Ambient temp is around 21 deg C depending how high my wife has the a/c. after I installed the F/fan the right way my temps got better. The intake fan(old one) is in the HD cage blowing air right over top. I used a/silver 5. I've since moved the sensor from the ram to the v/card, seems ok. It's temporary anyway 'cause I have the zalman zm80d hp coming any day now. I have pics to post but not sure how it's done, I clicked the button here on the post page but it wants a URL and I don't have one to give lol. here's the updated temps(surfing) case 31 cpu 34 hd 35 still unable to see memory temps due to the sensor not working. Still in touch with dell  |

Buz, Go to this site: www.imageshack.us/Upload your PICS using the Browser button. The Site will then give you the URL:http://xxx.xxxx.xxx. Copy this URL to place you can store it temporarily. Then when you click the Pic Link..... Copy and Paste the URL from the site. Should work fine as long as there under 850kb. T.RoW |
