DV9000t Fans on almost all of the time

I have a DV9000T with a Core 2 Duo T5500. My fans seem to be on most, if not all of the time, and not just the quietest fan mode, but a step up from that. Every review seems to say the fans are quiet and hardly go on but I have found the opposite to be true. Even when idling, the fans are on most of the time. The processor spends most of the time between 36 and 44 degrees with little or no CPU load, but this is with the fan on. Is there something wrong with my laptop or should the fans always be on?

Also, I have been running CPU clock utility and my CPU is almost always at 1GHz, so the CPU is stepping down ok. Although the strange thing about the program is that it shows my OS load at around 2-5% but the CPU load as 13-14%?

Any ideas?

 

The fan could be malfunctioning if you hear any variation of squeaking or whining, but if its just a tad bit louder theres propably nothing you can really do about it. Except trying to clean it out using a can of compressed air to clean out the dust to see if that helps to keep the computer cool enough so the fans can remain at a lower speed.

As for the load thing, I'd disregard it, OS load and CPU load are two very different things.

 

I think most of the 9000t problems is that the number 1 harddrive gets hot. I have had mine up to 55 or so when banging on it very hard without a chill pad. The CPU temps are very seldom get warm enough for the fans to come on.

With a chill pad my HD runs about 38 to 42 and the fan still comes on but not all of the time.

I use Speedfan and NHC to monitor my temps. Neither will control the fan though. Has anyone been able to make this work yet?

Battery life isn't really good for this model(probably any HP model). I can get about 2.5 hours using NHC but the fan coming has to be running it down more than necessary.

Can you share what is your HD model? I had 80Gb from Fujitsu and it is pretty cool and quite.

But other dv9000t with HD from other brand got hot and fan on easily.

 

I actually don't have the HD drive. The model number is 9030US. It has 2 - 100 gb 5400 drives. The second bay runs much cooler than bay 1.

I have a dv9000t, 5600 cpu, go7600, and 100Gb 7,200 rpm Seagate. With the Zalman cooler I get 28 on the CPU fand 36 on the HDD while sufring the Net. This cooler lowered my CPU and HDD temps 10 degrees.

 

I agree the Cooler will do what it is supposed to do. The concern I have though is for battery life. I generally don't run my cooler when on batteries. Its either going to be the internal fan or the cooler(plus the fan still kicks in) that eats my battery up.

I just wish the fan was controllable so I can run a little bit higher temps and save some battery while on the road. I don't do a whole when other than surfing and what not while on battery anyways.

Seems like a low temperature for the fan to be running.
Mine for example cycles on when the CPU reaches 60-C then turns itself off 30 seconds later at 52-C.
