xp is long gone

scodan reviewed v6.0b on Feb 19, 2004

You're not going to see ANY results under Windows XP, simply because that platform doesn't need CpuIdle; it has a built-in function that does the same exact thing. Windowx 9x is a different story.

Has anyone had any success using this program in Windows XP? I can't check my temp on my MoBo from windows. I'd like to hear your results.

6.0 Beta 6 adds finally 3 options to advanced chipset cooling, it finally works at all my systems, also i noticed problem with older K7 with 0.5 multipliers get better (and is known) ...

so my rating is going back to 4 (because no freeware for home use)

greeny` reviewed v6.0 Beta 6 on Oct 16, 2002

its kinda strange... version 6 doesnt work for me at all, it just has no cooling effect. i'm currently using 5.9 and it cools my cpu down from 51°C to about 42°C, thats why i'm giving it 5 stars.

ck42 reviewed v6.0 Beta 6 on Oct 15, 2002

Still using Beta3. Installed Beta6 and it no longer works.
Reinstalled Beta3 and it's working again.
I'll still give it 4 flaming turds because when it works, it works well.

CyberDoc999 reviewed v6.0 Alpha 4 on Jun 21, 2002

This works!
It took my temp down 10 degrees under windows 2000.
Great Program!

bsf reviewed v6.0 Alpha 4 on Jun 17, 2002

Well, the functions are very nice.
It cooled my CPU from idle 50C into idle 29C
Only one problem....
it's shareware.. not freeware.

wonko reviewed v6.0 Alpha on Jun 13, 2002

Didn't lower my CPU temp a single degree. In fact, my CPU temp went *up* several degrees while using CpuIdle. Also claimed it couldn't find Motherboard Monitor 5, even though MBM was installed and running at the time. Since NT/2000/XP already treat idle CPU time correctly (unlike 9x), I'm not sure why there's even a version of CpuIdle for non-Win9x users. It's completely unnecessary.

psychoactive1 reviewed v5.9 Final Beta on Jan 30, 2002

I've been using CPUIdle and CPUIdle pro on multiple platforms, and it's excellent. I push my machines hard and they are ALWAYS on. I monitor temps using software and embedded chipsets and external probes in key places on my systems. No probs, runs great, keeps my machines cool. If you have problems with it, it's likely you have a problem with your OS and/or operating environment.

PsychoPops reviewed v5.9 Beta on Jan 3, 2002

Well you guys were right It lowers the temp bout 10 degrees on an asus a7m with an athlon 1.4 problem is it makes my puter running xp very unstable lockups when I go to play games or when my screensaver runs I close cpu idle problem goes away Im bummed I liked the cpu running cooler but not at the expense of locking up to bad

mayakovski reviewed v5.8 Beta 6 on Apr 8, 2001

Very good program. I have an Abit BP6 with dual celeron 500s. When CpuIdle is running my temps are about 20 degrees lower than without it. Yes the CPU usage goes to 100%, that means with CpuIdle it is running in full pause mode. That is why it works so well.

manbeast67 reviewed v5.8 Beta 3 on Jan 21, 2001

This program has done wodners to stabalize the temperature on my computer. I have a dual 366 celeron machine on an A-Bit BP6. Both CPUs are overclocked to 500 and this program shows a noticable temperature drop of 5 to 10 degrees Celsius within minutes of starting it. And yes I have tried other methods of cooling the CPUs...i.e. sanding them flatter, there are 8 fans in my case, good heatsinks, etc.

vauger reviewed v5.8 Beta 1 on Jan 1, 2001

I run a Abit VP6 With one 933Mhz Intel PIII and after installing this program the temp on my system went from 29°C to 35°C, and i tested this while the system was in no use and only had the screen saver running, so i find this program doing no use for me but giving me the info on my cpu and not working when i installed it because the it was out of date. The cpu meter in Windows 2000 goes right to 100% when i run CPU Idle pro 5.8 Beta 8

bmw15 reviewed v5.8 Beta 1 on Dec 30, 2000

Ok, I know what I'm talking about. Its USELESS in a NT environment!! The NT Kernel runs the HLT command at idle. It may be a different story for dual+ processors, but I know for a fact thats its running already. My temp drops about 20 degrees when NT starts compared to just being in the bios. Look at the task manager at "System Idle Processes".

Lucifer : yes there is it's called CPUidle ;)

And for everyone who havn't tested this proggie and says it's useless REALLY ! Then stop commenting and go on with your daily lives or something.. It's working for me .. and cooling BOTH CPU's now with beta6 from 40 degrees to 27-30 degrees .. i'll be happy to post a screenshot from before and after the effect of CPUidle Pro .. it works .. and for those it dosn't though luck .. it's beta!

loucifer reviewed v1.0 Beta 6 on Dec 2, 1999

Well i havent rated this yet, but was curious to know is there a version of this program availabe for Win95/98 ?

lopharin reviewed v1.0 Beta 6 on Dec 1, 1999

Uhm, hate to say this, but that idle process in the processor list doesn't mean it's executing the HLT instruction. Novell has had an idle process in the Netware OS forever. It doesn't cool the CPU. Since CPUIdle Pro Beta 5 (even tho the author says tons of bugs were introduced) both my CPU temps dropped from 35C to 30C. As stated, the previous versions only really affected my second CPU. Not extreme, but 5 degrees is 5 degrees, I think that 30C is my sweet spot if you will. Win2k RC2/3 does not execute the HLT instruction. Before my GlobalWins, I was averaging 40-45C with icky coolers. The GlobalWin coolers reduced that down to 35C, and even lower at times of standard idleness. With CPUIdle Pro running, I'm a solid 30C or less (especially on my more idle second CPU). CPUIdle Pro works. If it isn't working for you, you are doing something wrong.

bmw15 reviewed v1.0 Beta 6 on Dec 1, 1999

Silly people. It won't work under NT4, or some version of Windows 2000 because it already has a program running to cool it. Look on the process manager on NT4, notice the very top running program, "Idle Processes"? Well thats the cooling program, so you don't need CPUIdle. Just to let you know.

krisp reviewed v1.0 Beta 4 on Nov 27, 1999

I also have a BP6 w/ dual 333's in Windows2000 RC3. I figured "why not try it?". Anyways, it only seems to work on the second processor (which happenes to be on sensor 1). I dont know why it does not idle the other processor also. Seems kinda pointless if it only cools one processor on a SMP system.

lopharin reviewed v1.0 Beta 4 on Nov 26, 1999

I don't know what you guys are whining about. It's working just fine on my BP6 with duallie Celery 400's. When the system idles, I sit right around 31C on both CPUs. When I'm hamming the boxen, I've yet to see it go above 35C. GlobalWins are part of the heat reduction I'm sure. :) But I do see CPUIdle Pro making a difference on BOTH CPUs.

Python reviewed v1.0 Beta 3 on Nov 26, 1999

Robin : yeah mine says 99 - 100 % all the time too .. but it does not work with DUAL .. my processors are in Win98 30 Degrees .. but 40 - 46 in Win2k .. this with the Idle program in Win2k saying 99 % does this say it works .. daaa
please back up such statements before you say something like that ..
Now im going to download this new program which hopefully will support both processors instead of just 1. And for the rest of you people PLEASE read all the reviews here before stating something ..

For fairness. I tried w98 version under PII 400 mhz, Windows 98 Second Edition. ATI All In Wonder 128.
It works fine ! ( So it was really a shock it did not work
at all for NT4. Should I try on Windows 2000 Professional 2183?)

yoni reviewed v1.0 Beta 3 on Nov 26, 1999

Good utility because it is really small and doesn't use too much ram. very easy to use and has some advanced features too.

Redox reviewed v1.0 on Nov 25, 1999

Ok, ok... CPU-Idle works (chills my celeron 464 back to about 21 degrees when it's just on doing nothing (AOpen HWmonitor)
And with TaskInfo you can see it work...

But IMHO 'Rain' is a much better cpu-cooler... no unnecessairy options, much less mem overhead :))

Skuld reviewed v1.0 on Nov 25, 1999

OK, see the matter : some files are missing. I think the good version will be available monday :-(
Sorry for all of this.

Python reviewed v1.0 on Nov 24, 1999

In case you didn't see my last msg. CPU idle dosn't work in Windows 2000 if you have DUAL processors .. or at least not with the Abit BP6 .. don't know with any other motherboards ..
I think that is the main reason why this proggy is made!
i at least hope .. because it only idles one of the processors .. but it's better than none of the processors !

One of the best pieces of software for overclocking.

hilbe reviewed v1.0 on Nov 24, 1999

According the the author, they disabled it since RC2. I'm not sure about it, so i asked him. With this program running, I know its cooling my CPU. Like I would rely on Microsoft to do it...they are the authors of the blue screen of death program (or feature maybe?) :)

BB88 reviewed v1.0 on Nov 24, 1999

Why not cool your CPU down and prolong its lifespan instead of helping others to decrypt some useless keys?
Good job CPUIdle, but don't NT/2000 have their own suspend instruction built-in?
