Cricket sound

When the fan is not working with full power I can hear "cricket sound" out of the left side of my computer (where the fan and the processor are). It's not at all loud but it is worrying, cos I don't don't know where exactly it's coming from and what effect could it have on my computer. Is there anything I could do to determine how demaging this could be?

 

if its on the leftt side of your laptop i assume that its the hdd working
it usually makes this kind of sounds while accesing drives
and when the arm moves over the disk
its nothing to worry about
if it really worries you try running hdd diagnostics to check if theres anything wrong

 

hdd seems to be fine, i checked it.
and i don't think the sound is coming from the hdd, it from cpu/fan department. It lasts for about half a second and then quits for a second before repeating the cycle. it's on at all times, it does not matter if computer is idle or not, it's just that when the fan is at full speed it's not audible anymore, cos the fan is louder.

well the important thing is that it's not the fan. everything else can be replaced under warranty if need may be, without loosing any precious data.

 

it could be the "cpu whine". when you hear the noise, try scrolling on a page. if the sound stutters, it is probably cpu noise. also, does this noise occur on battery or ac?

 

it's exactly as you've said. It takes a certain "rythm" that changes a bit when I start doing something - like scrolling a page.

And i can only hear it when on battery. didn't notice this before.

 

has all the symptoms of CPU whine syndrome.

Seriously though, the CPU whine sound is normal, though my puter's whine dosen't sound like crickets... can you get an audio recording of it?

 

Do a search on RMclock. Might lower / remove the sound for you. We had a pretty good sized thread on this topic about 4 months ago.

 

thank you pyro9219. i have found the thread and it helped a lot. i downloaded rmclock and set it following you instructions. i only set "performance on demand" when on battery, cos that's when the sound is noticable.

since I'm new to this stuff and have never heard of "undervolting" and "throttle" before and don't quite understand what the latter means I have a couple of questions:

1.) what are the cons of undervolting? There's a lot written about pros (no overheating, longer battery life) but I've found nothing on cons.

2.) what exactly is throttle and did I understand correctly when I set it like this:
performance on demand: throttling on levels 0-7 both times (AC and Battery), while PST on levels 0-4 both times
maximal performance: all on 4 (PST and ODCM)
power saving: all on 0

Anyways all the previous sound are gone, the fan is not all the time and all I can say is thank you.

EDIT: one more question. just out of curiosity. whay does speedfan show temperatures 15 degrees celsius lower tham RMclock?

 

after following the instructions on this forum how to eliminate the sounds such as the one i've had problems with in the previous posts of this thread plus the one i didn't know was there until i read about it here as well (the headphone sound) my computer become silent enough just to come up with another one, which was obviously left unheard because the fan and the sounds mentioned above.

it's my keyboard. when I type I can hear it squeek ever so slightly. the squeek is not there with the computer off, only when it on, so it's probably not a bending sound or something. anyone else noticed that? If it is the keys, can I expect them to wear off a bit after a while and I won't be disturbed by that sound again?

i work in a really quite environment, therefore I can hear every bit of sound that's a bit unusual or better yet, unexcpected.

 

1). thats because the only con is that if you go to low your system might be unstable. No physical harm can come from undervolting though. I'm telling you as someone that works at Intel, the lowest voltage supported by RMclock are fine .

2). Don't bother using throttle (ODCM), it's an older method of controlling the system, sort of the precursor that Intel was using to get some scaling into desktop systems thats just around from the earlier times of RMclock and for legacy systems like P4's that can't do anything else.
Just focus on the P-states. P-States work by changing the multiplier.

Simple example: If FSB = 100mhz and Multipliers can be 1/5/10. 100mhz * 1 = 100mhz processor, * 5 is 500mhz, and * 10 is of course 1000mhz.

A hint about heat = Voltage will cause average tempurature while current goes up with cpu load causing variable levels of heat. Lower processor usage and lower voltage together will cause a cooler system, which in turn lowers fan need.

To Set RMclock:
Performance on demand = all P-States
Maximum Performance = largest multiplier only (p-state)
Power Saving = lowest multiplier only (p-state)

I've never used speedfan, so I can't comment on that one. Maybe someone else can?

 

some people said that the con could be higher HDD and GPU temperatures, cos the fan also cools them. is this nonsense or does this apply to the so called "unstable system"

 

You HD and GPU might raise slightly, but the GPU has it's own cooler, and when on the desktop (web browsing, music, office stuff) it's not going to get high enough to trigger it's own cooling either way. The HD won't raise more then a degree or so if anything. Your system really shouldn't be thrashing the HD causing major heat unless you are doing something that requires the CPU, which means the cooling would be on anyways.

What I mean by the unstable system is that without enough voltage your registers inside the CPU could trigger improperly and it can cause gates to get temporarily stuck causing you to need a reboot. Dmitri (the author of RMclock) worked with people from both AMD and Intel to get the voltages set within safe limits for most of the chips produced. With anything though, there are a few oddballs that really need a little more or little less juice but that is easy to fix, just reboot and change the voltage.
