XPS 8930, T57JF Heatsink force full, connect sensor stop BIOS error

XPS 8930
i7-9700
WD Black NVMe 1TB SSD with heatsink
WD Blue sata 1TB SSD with 3.5 tray with fan
Seagate 7200 5TB
32GB ram
1660 Ti 6GB

Just got my new 8930 and have ordered the upgraded T57JF heatsink/fan off eBay.

But I'm wondering if I could buy (or make a harness) that would let me run the cpu fan at full all the time but keep the sensor connected to the header to avoid the BIOS error?

My room is already got a few fans and the extra noise won't bother me at all.

Thanks for the help

What would happen if you disconnected the 4th pin which if for PWM?

Would it just be running at 12volt and be able to sense the speed?

Well, It's interesting.

Both of the fans (cpu and upper) were standard wiring colors (blue is PWM which controls fan speed).

I used a small screw driver and bent the clip in the plug and pulled the blue wire out.

Both run at full speed all the time.

The stock CPU fan at full speed is hands down the loudest cpu fan I can ever remember (but my room is already loud so I don't notice it)

The case fan exhausts a TON of air.

Idle temps are around 80F/25C

I ran a benchmark and at 100% the hottest any cor got was 144F/63C

That doesn't seem unreasonable to me.

Oh the temp Readings were done with core temp

5 Minute stress test on Intel Extreme Tuning Utility Temp was always around 65C

@bbsux4evr  That doesn't seem unreasonable to me.

It is not unreasonable for a CPU @ 65 watt TDP.

Once you get the new blower style fan/heatsink installed, the CPU blower fan will not need to run at 100%, as long as you have a 120mm top exhaust fan. If you do not have a 120mm top exhaust fan, you should make that upgrade at the same time as your blower style fan/heatsink install. Be sure to have thermal paste on hand.

@bbsux4evr   What would happen if you disconnected the 4th pin which if for PWM?

That would turn it into a 3-pin fan . . . and 3-pin fans do not throw the BIOS start-up error.

I’ve got the fan on order. Should I use it as a 3 pin and the cpu fan as 4?  Or both as 4?

For the CPU blower fan, I would leave it at 4-pin. For the 120mm top exhaust fan, it would depend what fan you ordered. If it is a quiet fan at 100% rpm, then there is no need to slow it down with modulation (Noctua FLX). If it is a loud fan or has a particularly high rpm, then you might want to use 4-pin, so it only roars when necessary. You will also need to order the Aurora R5/6/7 top exhaust fan bracket for your 120mm fan, if you are upgrading from a 92mm top exhaust fan.

I'm looking over the pics of the Mainboard (can't open my case at the moment).

Is there a header for the front case fan?  (If not fine by me, I'll probably get a sata power to fan speed controller (or just a straight 12volt harness) for multi fans and hook both the case fans to it.
