Aurora R4 System Fan Issue

About 5 months ago my system fan RPM began ramping up to around 4,000 when playing games, it normally would idle around 1200, and go up to around 2,000 when gaming and still remain very quiet. When it runs at 4,000 rpm it sounds like a miniature jet engine. I cleaned everything out really well and it alleviated the issue, now about 5 days ago this issue cropped up again, but this time it ramps up even when I'm just browsing the internet or watching a video. I made sure to thoroughly clean out the system again, even though it wasn't that dusty. The Ambient Temperature sensors seem to be in working order, the CPU pump is running fine as far as I can tell. Also I have not modified the bios from what shipped default.   I have been browsing these forums, and various other forums on the net the past several days trying to find something that would possibly give me a clue as to what is wrong. I have tried adding a bit of thermal paste, reinstalling the alienware command center and the power dissapation technique, but all to no avail. Now I did try to run the EPSA and did not see an option to test the mio board listed. I am leaning towards it being a bad mio board that needs replacing, but I'm no expert and while I have been a long time customer of dell, and this is my second alienware pc, I am at a loss as to what the root cause of this is. I would appreciate any assistance in finding a solution to this issue.

Thanks for the encouragement Morblore. Also thanks Rajesh, I have cleaned out the case and all the fans quite thoroughly and had already ran the dell diagnostic utility from the website, and the epsa and "everything" tested fine.

I have the A3 bios currently and downloaded the A5, A6 and A7 and have them on a flash drive, is there something I need to do to be able to boot from the flash drive or run the bios updates from it? I don't have much experience in this area and could not find the information on the bios page other than it saying put them on a dos bootable flash drive.

Hi,

The BIOS packages can be opened in windows. You should be able to update from BIOS A03 to BIOS A05 and then to BIOS A07.

Try the power drain:

-Remove AC adapter

-Press and Hold the power button for 30 seconds

If the problem persists and you're located in US or Canada, send me private message to get the problem fixed.

Well unfortunately that did not fix the problem, it still persists. Now this is a bit silly, but I don't see where I can sent a pm on here.

Click on my user, then you can click on start a conversation. If that doesn't work, send me a friend request.

After some trouble shooting, it was determined that the mio control board and the liquid cooling system needed replacement, both parts have been replaced and my problem is completely resolved. Alexander was a considerable help in this process.

Hello, (sorry wasnt able to find how to send a pm, new to this site.) I am having a very similar issue with my pc. I have been checking through forums and I have tried everything they suggest. I have contacted Dell tech support 2 times. the first guy was very helpful, tried a few things and told me he would email me the next day to check if it was working. he never contacted me and i didnt catch his name. I called again a couple days later and the next guy tells me theres nothing wrong and doesnt seem to even want to look at it. this issue started 5 days ago, i know its not normal.  I have a hard time talking on the phone and would much rather talk to a alienware tech through email or something. I see you have alot of knowledge and I was wondering if you would be willing to help? I know i should make my own thread, but i wanted to ask you first. I just dont know what else to try.. my computers not even a year old yet..

thanks, hope you can help.
