dv7t cpu fan problems?

My laptop arrived yesterday. I noticed that the fan is also always ON but on a low rpm. Disabling 'fan always on' option at the bios didn't do anything. The fan is still on all the time, again low rpm. I called customer service and we did bios upgrade, bios reset, and acpi uninstall/reinstall.. Nothing changed.

I have done another test.. I haven't heard the fan go on high speed yet. I tried playing 6 quicktime videos simultaneously and did my matlab simulation at the same time. I ran this for probably 10-15 minutes. cpu is running 100% all the time during this test. But my fan didn't increase speed. It stayed the same. the cpu temperature monitor that I have is always stuck on a certain value after the bios upgrade. I have read forums and they said that same thing happened to them, cpu temp monitoring will stop working after the bios upgrade.

From this forum, fan that is always ON on low rpm is fine.. But do you think the test that I did wasn't enough to raise the temp of the cpu and make the fan go to higher rpm?

Thanks!

 

100% usage should be enough to make the fan speed up. I think that maybe the faulty CPU sensor cause's problems with heating they need to fix the bios.

 

No, 100% cpu usage is not enough to make the fan speed go up.

If its anything like my HDX16T, you need to SERIOUSLY be giving it a work out to raise the heat high enough for the fan to go higher.

Mine idles at about 28-30c, internet browsing 33c. The fan doesnt step up until it needs to, which is about 65-70c+. to get to that point, i tried:

Encoding a video, opened 5 instances of firefox running youtube videos, doing a wprime 1024 test, skype, utorrent, titan chess, and a couple other programs for good measure. it took FOREVER to get to that temperature, which is freaking AWESOME.

All i wanted to do was see how loud the fan is on full blast.

PS, if you want to see your temp, install rmclock

 

I called technical support 3x yesterday and I was able to talk to 3 different people. I relayed to each of them the exact problem(?) that I might be having regarding the cpu fan and each tried a different fix. They tried to give explanations like faulty temp sensor, thermal/heatsink problems, corupt bios, etc. Though they have different explanations about the problem, everybody recommended that the laptop be repaired. Each of them offered help for me to send the laptop to their service center. I just had this laptop for two days and if I have it repaired, it was like I purchased a defective laptop for more than a thousand bucks and had it fixed for free....
