Solved Burning PLA and it's leaking onto my prints

I recently had the fan that blows on my heatsink for the hotend go bad, and Robo was nice enough to send me a new one with a new mount.

I've installed that, but can't find a good mount for the fan that blows at the extruder (need to print a fan duct for the stock hotend).

I've replaced that with just a desk fan for now, and now my prints are getting globs of burnt PLA all over them. It appears to be collecting on the square above the actual extrusion point, overheating, and falling onto the print.

My questions:
Should the fan blow towards the heatsink or away from it? I currently am blowing towards.

Is it possible that the desk fan is making the thermistor read too low, causing the entire thing to overheat and drip PLA?

What else could be causing it, and how do I troubleshoot?

I should note I'm printing at the same temps with the same filament that has had successful prints. The only changes are the fans. It's possible they aren't the cause, and I just can't think of what else it could be.

Thanks!

 

If the heatbreak is the issue, how do I resolve that? Buy parts or is it just something that needs to be tightened?

 

Thank you, I'll get to work on it tonight. It's so hard to know the right terms to find similar repairs.
