Windows 7: DV6 gadget and cooling fan problems

DV6 gadget and cooling fan problems

I have a HP DV6 that is about 2 years old. Ever since new the fan has run at a very high sound level (think NASA wind tunnel) but the DV6 was running very warm so I figured that this was a normal, albeit unpleasant condition. After an 18 hour downtime (normally it is always on and booted-necessary rebooting is always done immediately so no down time) and after rebooting the fan was making strange noises-like bearing vibration. After a while it settled down to a much lower sound level but the heat level had risen to a very high level. Upon the next reboot I got the message that there was a fan failure and I reboot at my own risk with risk for system shutdown. As I was trying to solve my other (gadget) problem I decided to try anyway. The gadget problem is that some of them donīt show correctly and there is a magenta background that shoudnīt be on some of them. This problem occured after the first reboot after the system downtime. I ran several cleaning and repair programs with rebooting inbetween sometimes hoping something would help. Finally I ended up with the situation that the fan is running at about the same sound level, albeit not running completely smoothly, as my DV7 which sits right next to it and the heat level is just a little warmer than the DV7 but much cooler than anytime before! This seems like it would be a normal operating condition but Iīm scared to death of having to reboot and having the old problems returning. So, to my questions: how do I fix my gadgets and why have I had fan/heat problems for such a long time? Is this a software problem that has resolved itself? As I said the fan is not running completely smoothly but there is no high temperature problem as before. What to do?

Which fan is making the noise or running fast?

Regarding the gadgets, if you have installed Internet Explorer 11, and have changed your screen text size to other than 100%, some gadgets will not render properly.

As far as I know I only have one fan which is located on the left hand side. I have IE 11, how do I set my screen text size to 100% (Iīm a newbee to most of this stuff, so please be gentle with me)? Thanks

Thatīs the ticket! I was set on 110% instead of 100%. Changing to 100% gave me back my disfigured gadgets. Thanks for the link! Now if I could only fix the fan problem. Iīm getting the bsod now.

Just google to replace the fan. The whole line has overheating problems so there should be a big Google results list for your model replacement fan and probably even videos for how to replace it. Prices might even be reasonable.

If you have to do a lot of disassembly to get to it, then I'd consider also repasting the processor which should cool it down. It's risky and a huge project, too expensive to have anyone else do it due to time and complication. Most units have videos and tutorials online showing how.

However if the fan is easily enough replaced without going that deep into disassembly, you can also consider a cooling pad which might lengthen its life and avoid the risks of complete disassembly if required to reach the CPU.

I have purchased a new fan/heatsink (# 650797-001), should be here in about two weeks. I have cleaned the air vents by using compressed air and vacuum cleaner by blowing/sucking on all the vents. Now the fan is running much quieter albeit with a ragged fan noise (thatīs why Iīm changing it) and the present core temp. on the 4 cores is between 59-80 degrees C., before the temp. was so high that I could not touch the underside without risk of burning my hand, so the question is: as I have read that overly high temps. can cause solder joint failure and component shifting, should I also change the mother board (# 665342-001 if Iīm not mistaken) as well as I must completely disassemble the dv6 to get to the fan anyway? I have the dv6 Maintence and Service Guide and have spent a lot of time on Youtube watching as many demont./mont. videos as I can, so I donīt think the job is insurmountable (I even have a guitar pick to help pry parts apart!).
