GTX 465 stock fan cord came loose; now BSOD upon entering Windows?

The stock fan cable on the Zotac GTX 465 are really, really flimsy and I guess I managed to somehow pull one away from the connector, now the fan won't spin (I'd like to say it wasn't my fault because I don't specifically remember it happening, but who knows).

Basically now the fan doesn't come on and when I enter Windows, there's about a 3 second delay and then a BSOD followed by a reset. I contact Zotac and they told me to RMA the card which I'm going to anyway (the copper pipes on the base of the heatsink are bent and dented from the get-go), but I was under the impression that these cards didn't necessarily need something plugged into the auxillary power/fan outlet in order to work properly. The mosfets behind the fan aren't very hot once Windows loads and restarts, so I don't think it's a heat issue.

Is the stock cooling fan cord so important that it'll cause the screen to crash right upon entering Windows? The main reason I'm asking is because it seems like it occurs right when Afterburner normally 'auto-adjusts' my clocks and speed. The downfall is that I can't get into safe mode to disable Afterburner, which is what's causing me to think this may be something unrelated to the fan plug/cord situation. If anyone has any input, please help me out. Thanks in advance.

P.S. I forgot to mention that I have a fan mounted on the unshrouded heatsink, so the GPU temperatures are fine. The only temperatures that might be getting a little high are around the mosfets, but just putting the back of my hand to do the card once the BSOD occurs proves that heat isn't the issue. I'm thinking the card is trying to send volts to the fan and since the fan isn't plugged in, it's causing the BSOD. I could be wrong, though. Please help me out; if I could get around with without having to RMA, I'd much rather do that as I've heard it takes Zotac a long time to get around to RMA'ing their products.

So in essence if that stock cooler fan isn't plugged into the card, it will cause the card problems, correct? Because I have a fan mounted onto the radiator-like heatsink underneath the GTX 465's shroud, so the card is getting plenty of airflow surrounding the GPU. The only part not getting airflow is where the normal stock fan is at (towards the 'right' end of the card).

I'm just trying to figure out if taking the plug out of the fan entirely is causing the problem, os if it's something else. If I can take the plug out and still run the card fine provided I have decent cooling for that part of the card, I can work-around this. If not, then yes, I'll definitely have to get a replacement fan for the card.

Does that clear anything up?

With a 3 second window before a BSOD it's hard to tell for sure, but I'd say there's a very good chance you're still overheating your card even with the modifications you made. I've never heard of a faulty fan directly causing a BSOD, though it would be quite simple to unplug it and test that assumption.
