CPU fan on Inspiron motherboard issues
Hey everyone, I have a hobby of flipping computers, and am doing a very low cost gaming PC build. For this build I bought a bundle that included an Intel Core i5-2400, 4gb ram, a Dell 0GDG8Y (inspiron) motherboard, and a standard Dell cooler. I replaced the 2x2gb ram stick with 2x4gb sticks.
Upon startnig up the computer, the CPU fan get absurdly loud, but eventually tones back down.
Basically, this is really obnoxious and it happens in windows too.
I've found out this:
When my CPU get's to around 30% usage, the fan gets loud.
When the fan it quiet, it spins at about 700-800 rpm.
When it's loud, it spins at about 3000-4000 rpm, sometimes more.
In the BIOS this computer passed all the tests, except for the "case fan" test. I have a 120mm blue LED fan connected to the front 3 pin connector, and an 80mm connected to the 3 pin on the back of the board.
I've tried setting a fan curve with SpeedFan and MSI afterburner, none of them seem to work.
I can't find a setting in BIOs to adjust the fan speed.
I can get the fan to only run at ~700 rpm in speedfan, nothing else. This is quiet but not enough to cool my CPU.
I've tried 4 different fans that i've had spare and they all have the same problem.
I've even bought 2 of these combos, both have the same issue, which leads me to believe it's not an issue with the motherboards being damaged or whatever.
Any idea how to fix this? I'm getting very desperate and don't want to go over budget.
Here's my full system specs:
i5-2400
EVGA GTX 670 FTW 2gb
8gb DDR3
Dell 0GDG8Y Motherboard
Standard Dell cooler
Rosewill Ranger M case
EVGA 600 W1 power supply
500gb Dell 7.2k RPM 32mb Hard Drive
Thanks in advance

And Inspiron 620 too. Both use same version of BIOS...

Is this motherboard from either an Inspiron 620 or a Vostro 260? What version of BIOS is installed? The latest version for the Inspiron 620 and Vostro 260 motherboard is BIOS MS-A08 which, quote: "Fix system will have some fan noise with some particular situations."
Dell OEM CPU fans are typically wired differently from after-market fans, to allow BIOS to control fan speed. So that may be part of your problem.
Since you do this as a hobby, is it safe to assume you applied fresh thermal paste between top of CPU and bottom of heat sink?
What version of Windows?
High velocity CPU fans at boot can be related to delayed or corrupted video drivers so look for an update from EVGA.
And do you have the latest Intel chipset installed?

Vostro 260 0GDG8Y
Dell fan wires are swapped round.

Several Dell models have jumper magic. Depending on which cables are attached it will say its Vostro or Inspiron or XPS aka Vostro 460/XPS 8300 Y2MRG for example.
Will also have Front panel Disconnected errors when cables are not attached.

Oh wow. Sorry. I didn’t see any of these replies! It’s my first time posting on this site haha.
So I talked with the ”tech experts” and they basically said “get an OEM fan,” which I have noticed that the wired on my fan are the standard layout, not the wacky dell one.
So do you guys now where I can buy an OEM heatsink and fan?

Just Google for either Vostro 260 or Inspiron 620 heatsink and fan...

Wait for the 4 pin fans in the one on then left the Dell proprietary or the one on the right?
also, about that front IO thing you were talking about, can you elaborate on that? All I connected was the power button switch. Nothing else.
Also as a follow up question for all of this, my front case fan is connected to the 3 pin on the motherboard and it only turns on sometimes. If i restart the computer from windows it won’t turn back on too.

@speedstep @RoHe
So hey sorry for coming back to this, but the problem is still there.
I'm gonna call the black yellow green blue pinout the "green pinout" and the other one the red pinout.
I have coolers that use the green and red pinout.
So the red pinout is the one used for Dell machines right? I have a fan with the red pinout but it still has this problem.
Should i try a green pinout fan? or will that damage the fan/motherboard?
Also I tried to use the intel stock cooler on this and that seems to work fine. It just spins at around 2000 RPM and stays there. This intel cooler uses the green pinout though, so is that bad?

There is no pinout. I'm not going to get into wire by wire connector by connector. Front panel and USB and Audio and and and and. Its not a water chicken install and its not standard. Its not documented.
Dell doesn't use fans differently than others.
They do sometimes wire them differently.
The problem is when you plug a Y cable for 2 fans where one is wired standard and the other is wired Dell you fry the input sensor with 12v where a 5v tach signal should be.
Thats why all it takes for some fans is a cable that swaps the wires back.

This is NOT ALL DELLS ALL MODELS ALL THE TIME ALL PORTS.
They have also started making all the wires black so you cant see what is what.

YELLOW TACH
RED 12V

So you’re saying I should get an adapter? Any idea where I’d find one of those? Do I just look up “Dell 4 pin to 4 pin” or something?

The 620S motherboard has specific fan.

Yes, I literally have two of those coolers. They both have the same problem. I’ve tried both of them

I have the same problem, same motherboard and oem cpu cooler and fan, but it is still running at full speed no matter what. It didn't do this when it was in its original case, I only swapped the case, everything works, but the fan is nuts! Did you have a solution?

In my Inspiron 620 motherboard I was helped by a new bios:

I had version A04, version A10 installed.
