I am keeping the original Dell motherboard. I have replaced the Dell proprietary heat sink and retention solution with a standard Intel retention bracket. Upgraded the Northwood P4 3.0GHz processor to a Northwood P4 3.4GHz. Removed the CPU shroud, added a Zalman CNPS9500 CPU cooler with Artic Silver 5 thermal compound and replaced both rear case fans with two Antec 75009 92mm fans (variable speed with built-in temperature sensor) oriented to expel air from the case.

Currently without installing the front fans and with the Artic Silver 5 not yet having time to cure I am seeing over 10 C decrease in CPU and case temps.. I also have > 5 C decrease in my video card GPU temps just from the increased airflow through the removal of the CPU shroud and the rear fan changes.

I still have the Dell case fans plugged in to their motherboard headers to avoid fan failure messages.. I am waiting for the 3 “Dell Fan Terminator for use with SlotWonder: This is a jumper that will fix any Dell that receives the ‘Fan Failure’ error at boot up." which I ordered from www.powerleap.com to arrive so I can ditch the Dell fans.

I have 2 Antec LED80XFAN 80mm Blue LED Case Fans ready to mount in the front of the case as you have done. Apart from the reconfiguration of the hard drive rails, how did you attach the front fans to the case?
Wow I forgot about this thread.

You can disable the fan error in the BIOS, disable Keyboard Error Reporting
What Bios version are you on? I think I'm on AO7
Yeah man I was totally shocked when I analyzed the OEM cooling.
I was like *** mate.
My XPS has run its course, I have a TT Armor thats waiting for a board so I can slap my E6700 in and get modern for a coupla months.
If I could get a few more Blueribbons over on the eVGA forums I'd get a 680I.
The mods have been pretty stingy lately with BR's though
Lemme know if you have any more questions.
I wanna know what your CPU loads at with the 9500.

EDIT--> What vidcard do you have?

BIOS is "Dimension XPS G2 A06 System BIOS" from 10/1/2004 which is the most current according to the dell site..

Video card is
XFX PVT43ANDF3 GeForce 6600GT 128MB GDDR3 AGP 8X
I've had it about a year and a half.. I mostly play RTS style games on the computer so it has been plenty good with my dual head set up.. I use my Xbox 360 for most of my other gaming..

I'll post some temps for the CPU when I get home tonight.. those fan terminators should have come in the mail so I can finally get rid of the OEM fans bouncing around.. I'm liking the Zalmans a lot.. I have three other systems (2U rack mounted) with ZALMAN CNPS7000B-Cu LED coolers but with the XPS case having so much extra headroom and newegg having a sale I decided to go for the ZALMAN CNPS9500 LED 92mm

You're right AO6.
Did you disable keyboard error reporting in the bios?
How on earth did you find this thread?

I found the thread somehow while searching for "XPS Gen2" and I think "Fan Error" but I have been searching for cooling related XPS Gen2 stuff all over the internet..

I found out the powerleap fan terminators work with the black/red/white fan connectors but not the black/red/yellow speed controlled fans like the two in the rear.. so I was still getting the fan failure error.. the "Disable Keyboard Error Reporting" took care of that though..

Ok.. so I mounted the two Antec 80mm Blue LED fans in the front after making the hard drive rail modifications you suggested.. I have the ZALMAN CNPS9500 going at full speed and I used its fan speed controller to dial down the speed on the front fans until I couldn't hear them anymore.. I think they are at around 1/2 speed.. the rear fans have their own speed control/temp sensor so that's all set.. My only remaining issue is cable clutter restricting airflow and trying to get into the 9500's fan.. I ordered some round cables from newegg and am going to go through with some cable zip ties and tie everything up this weekend..

Here are the original and new temps I used the Prime95 Torture Test to generate some heat.. Ambient room temp was 20C..

___________Orig_Config___________New_Config
___________/w_3.0GHz_P4_________/w_3.4GHz_P4
___________________TortureTest________TortureTest
___________Idle_____10min________Idle__10min__50mi n
CPU________41______53___________31____41____41
Mainboard___37______39___________31____35____35
GPU________66______65___________59____61____61
HDD1_______42______41___________28____29____29
HDD2_______29______37___________21____27____29

It's crazy because my load temps now with the 3.4GHz are the same as my old idle temp was with the 3.0GHz and stock cooling.. I'm really impressed.. Also, It's only been a couple of days so I am hoping that the Artic Silver will cure and lower the temps even more..

Thanks for the help
