Re: E530 - pulsing/whiny fan @ no/low load

Althea or anybody - so after setting maximum processor state to 90%, the notebook can be called quiet in idle or under low load (browsing, playing music etc.)? I'm seriously considering buying it and if slight lowering the processor power can make this notebok quiet, I'm completely ok with it. Thanks in advance for your reply.

Yes. In fact, you can set it to 99%, and it will be quiet under idle and low load. The problem is essentially that when running single threaded program, the cpu boosts its clockspeed to 2.8 GHz, a boost of 700 MHz. This causes the run to immedietely run. Setting the power management to 99% prevents this from occuring, leaving you with a quiet computer.

Of course, if you are running intensive work that's single-threaded, consider switching back to the balanced power plan (or uncap the max cpu speed) to get a boost.

This can also be generalized to more scenarios if you don't mind lowering the cpu speed. If your computer is too noisy, then just lower the cpu speed. I tend to have multiple cpu plans which I switch between as necessary.

 

But, as for your question, with 99% at low or idle speeds, it remains quiet, all the time.

Thank you Althea! I'm still considering buying as well..  Its between this and an x220 that's listed for almost the same price..  I like the E430 for screen and optical drive, so this is good news and I'll compare both for my needs now.. Thanks!!!

Just go with another model or better with another brand. This one is stil noisy. Now in summer pulsing is still very annoying for example when scrolling web page etc.

OK, so I've got my E430, no pulsing so far so I'm not sure if I should update the bios. Anyway, what I'm not very happy about is the fact that when the fan starts spinning under load it doesn't stop or slow down when the load is over. For example when I run Furmark, the fan spins up, then I stop Furmark but the fan doesn't seem to notice and keeps spinning with the same speed even after a couple of minutes when the temperatures drop down. Would updating the bios help with this?

That is the exact same problem that users have reported with the newest bios.

Thank you all for your help and for all the info on this thread; you guys saved me endless frustration.  I found an x220 for the same price and it works for what I need (I'm a mom and student) and I love it.  I had been set on buying the E430 until I found this thread.  

 

Thanks again and I hope that you all get a final fix for the fan issue.

I see. So if my fan doesn't pulse (or it hasn't so far) is there some other benefit of new bios? I don't want to take the risk of updating without a reason since I can still return the laptop for a full refund so I don't want anything to go wrong :)

 

Btw. I found out that when turned upside down the notebook is much more quieter because the fan's whirring is gone :D

Hey guys, this is a bitter irony, please check out Reason #3 to buy Lenovo, no comment...
