Aurora R5, loud and constant fan noise since upgrading CPU
Hello,
I've had an Aurora R5 for some time now, but decided to upgrade it recently.
I replaced the graphic card with a GTX 1660 and everything was fine.
Then, I replaced the CPU from the i5-6400 the computer came with, with an i7-6700K.
Since then, the computer makes a very loud fan noise. The noise is constant, and doesn't change whether the CPU is heavily used (temperatures up to 80°C) or idle (temperatures <40°C).
It doesn't seem to me like an overheating issue, and I have already tried to remove, clean and re-install the CPU fan, with no visible change.
Is there a way to diagnose where the problem comes from, and do I need to change something else in the computer (CPU/case fan, PSU...)?
Thank you in advance.

Vrm heatsink pictured below the "corsair" block.
Also, corsair h60 with an ml120 pro is compatible with the 6700k and R5.

Also, you need a vrm heaksink. Dell sold k class processors with a vrm heatsink on the motherboard. I believe with the Aurora R5, non k options did not include the vrm heatsink.

Yes, the stock fan cooler cannot support a k class processor, especially a 6700k. The fan/heatsink is only rated for about 65w. You need to upgrade to liquid cooling. Dell did not sell the 6700k with air cooling.

Thank you very much!
So, I could install this liquid cooler, but I also need to install heat sinks?
Is it possible/easy to install heat sinks in the aurora r5?
Sorry for all the questions, I have no experience with this!

You can get the heatsink on ebay:

It's just the two screws go into the motherboard, plus you put a thermal pad under the heatsink to help transfer heat.

Thank you for the link!
Unfortunately, I am not from the US (I'm in Germany), and would rather avoid ordering something from the other side of the world (especially since it would only arrive in 1-3 months), and I can't find the exact model from Alienware here.
Could I use some of these standard heatsink instead, without the screws but just gluing them with thermal paste?

Thank you so much for your help!

Yes, thermal tape plus mini copper mosfet heatsinks are another way to go.
