E1705 Temperature levels

Ok. This is crazy. I have had this laptop for about a year and a half now. Virtually no blue screens and I did find that the Memory Parity Error that I got before was due to my atheros based card and extremely buggy drivers. Not due to the OS or anything else for that matter. Anyways the temperatures are crazy high for the GPU for doing nothing more than idle work. Here are the temps that I8KFanGui are reporting...

CPU: 50C (Peak 57C)
GPU: 73C (Peak 74C)
Memory: 56C (Peak 57C)
Chipset: 54C (Peak 55C)
Hard Drive: 46C (Peak 46C)

Right now my fans are on high trying to get this heat out of the system and on at least one occasion my GPU has exceeded 90C. I8KFanGui has been set to add 8C to whatever reading that it gets from GPU. This put it in line with every other utility that reports the GPU temperature. Apart from tearing down my laptop and doing a dust cleaning is there anything else that I can do that will help to cool down my system? Any good external coolers to assist with the airflow?

P.S. - I have replaced my wireless adapter and my system runs with 3GB of ram. My video card uses an unlocked bios but does run on stock speeds -- It is not overclocked at all.

EDIT: Ok. I just took apart my laptop and cleaned the fans out. Found a dust ball (yes -- a solid dust ball) stuck in the gpu fan. That may of been keeping it from running effectively. I also can hear it rattling sometimes when running. Anyways on bootup the CPU reads at 55C and the GPU runs at 67C. I forced the fans to high and the CPU has dropped to 33C and the GPU to 55C. I remember having that before however the CPU fan seems to be running far more effectively. Any ideas?

 

Believe it or not.. those temps are around normal. I wouldn't worry about it, especially since you said you cleaned out the vents.

 

Ok. Right now my CPU is sitting at 33C and my GPU at 64C. This is idle. Virtually no load at all.

 

Ok. Since I last posted I noticed a weird issue. If I have the laptop lid shut for an extended period of time ( over 3 hours ) then the GPU seems to get very hot. I8KFanGui reports that the temperature exceeds 85C. It also seems that the GPU side fan does not kick in. The CPU side however remains at below 40C. Any more ideas?

Yep. I was right. My GPU fan is not running at all. I opened it back up and lifted the fan out of it's holding area and found that dust ball still in there although out of the way now. I removed it and put it back in. I did another test and the Video fan failed now. It looks like it just kicked the bucket. Noting that I only removed the two screws and not the actual power connector since it was snug in there. There is no difference in fan noise either so that fan may of not of been working correctly for several months now before finally "kicking the bucket".

Noting all this I8KFanGui still seems to get ghost readings of above 3000RPMs from that fan for some reason. Possibly the CPU side running long enough to cause a draft over there and get it that high. Not sure. I'm going to try and get Dell to send a new GPU side fan or a pair of them if possible. My laptop is still under warranty.

EDIT: Ok. Just got done with Dell and they are replacing my card. However they stated that the Nvidia card that I got with my laptop is currently no longer in stock and offering to replace it with an equivalent ATI card. The only one I was aware of was the X1400. Was a better one released later on in the product life?
