Intel P4 2.4GHz reaching 71c/160f

[jekk]

Hi everyone,
I recently built a new system, running a P4 2.4GHz (check my rig for complete details). The problem is that the CPU gets very hot, with NO overclocking (133x18.0,1.575v):

Using the original Intel fan (CPU came boxed with fan) I was getting ~2200RPM, CPU idle temp ~55c/131f, high load (like encoding Ogg files) temp sometimes got to 80c/176f!

I decided to get a new CPU fan cause this one was clearly rotating too slow.
I got a Vantec AeroFlow VP4-C7040, set it up and now i'm getting ~4100RPM (should be 4500 according to the specs), CPU idle temp ~50c/122f, high load temp upto 71c/160f.

This still seems too hot. The fan is set-up correctly, using the thermal paste that came with it. There are 5 generic fans inside the case (3 intake) which provide some air flow. There are also 2 fans inside the PSU, and a fan on the DPS (Dual Power System) board, and they all work, so I really don't see a reason for the CPU to get so hot! Any ideas what could cause this? I'm afraid to play games or go to high load to not damage the CPU. It really sucks to have a new computer and not be able to juice it properly :frown: . I was sure that with this kickass fan I wouldn't pass 60c.

Thanks in advance for any help. I'm really desperate!

What is your system temp?

 

[shock311]

hmm, I also have a 2.4 with a vantec aeroflow and I believe stock specs is 5400-5500 rpms, thats very strange that you are getting these readings, I have a sinxp1394 and i'm getting 31C idle. how many different temp sensor programs are you using, I'm using speed fan primarily but then also check with Aida. Maybe the readings are off or can you really feel how hot the processor is?

 

[Chrisdragon]

Did you use a THIN layer of thermal grease/arctic silver 3 on the CPU core?

 

[jekk]

Nerdwannabe: Sandra reads motherboard temp at 34c/93f.

shock311: The packaging I have says 4500RPM, but I don't seem to get past 4200. I have an SINXP1394 myself as well, and I'm getting the temp readings using the bundeled GigaByte software - EasyTune4, as well as SiSoft Sanra. The BIOS health monitor also read 2200RPM with the Intel fan and 4100 with the VanTec, and ~50c when idle so I don't think that these are false readings.

Chrisdragon: I actually used a thick layer of paste. But since the temp was very high when using the Intel fan (which comes with a set amount of substance), I don't think that that's the cause. I will, however, remove some paste and see how it affects the temp.

I removed some grease, leaving but a thin layer. Sadly, the tempratures seem to be the same.
I'm getting the same readings using SpeedFan 4.0.8.

My Abit BH7 displays the common characteristic among Abit boards with high temp readings, as related to other boards with similiar configurations. I found this at the Abit FAQ site:

Is the CPU temperature too high? Why is the CPU temperature of my ABIT motherboard higher than some other motherboard with the same chipset? (ABIT P4 mainboards)



The way CPU temperature measured in the BIOS or in the hardware monitor is through an I/O chip on the motherboard. That I/O chip probes a voltage given by the CPU thermal diode, and then BIOS / hardware monitor reads this value and uses some mathematical way to calculate the approximate temperature. According to Intel, there is another temperature sensing diode, which is responsible for the CPU overheating protection. When the CPU junction temperature reaches approximately 135 degrees Celsius (275 degrees F), the processor will turn down itself. That is, we can say the CPU is quite safe if it is less then 135 degrees Celsius (275 degrees F).

Since the temperature is ?calculated?, not ?measured?, the formula which the BIOS uses will make the outcome different. There is a parameter that is provided by the I/O chip vender, which we expect it to be the standard, so we use this parameter to calculate the temperature of the processor. Once this parameter in the BIOS is changed, the temperature shown in the BIOS PC health or in the hardware monitor tool will be altered. But, in the mean time, the actual temperature of the CPU is still the same. So the temperature you saw might be higher comparing to other motherboard with the same chipset, it is because we use the different parameter to calculate the temperature. We cannot say that we are more accurate, but we sure follow the standard provided by the I/O chip vender, and we believe it should be the proper one.

Based on the test in our lab with following conditions, the average CPU temperature in idle state is below 50 degrees C (122 degrees F); meanwhile; it is below 75 degrees C (167 degrees F) while heavy loading. The CPU temperature is affected by room temperature, chassis temperature, CPU fan and other heat source inside the chassis. If the reading is higher than our data, please consider doing some improvement for heat dissipation.

Room temperature: 25 degrees C (77 degrees F)
Chassis temperature: 35 degrees C (90 degrees F)
A good chassis with two 12 CM system fans; one draws air into the chassis and the other exhausts hot air outside the chassis.
A strong CPU fan
The "CPU Shutdown Temperature" in "PC Health Status" page could be enabled and set to 90 degrees C (194 degrees F). In case there are something wrong with the system like CPU fan stops or drops off from CPU retention unit, the ACPI compatible operation system could shut down itself to prevent the system crash and other damages. But, if the operation system fails to shut down, there still be a final insurance that CPU will turn itself down at 135 degrees C (275 degrees F) and the system will be powered off immediately.

[vaporize]

so TATES, are ABIT mobos bad for overclocking? I am thinking of getting the abit ic7 and 2.6C, Should I reconsider?

 

[Corporate Thug]

abits are usually a great ocing board, go with the IC7

 

[jekk]

If (according to abit) 75c in high load is normal, why do all temp monitors start freaking out at 50-60c?

But still my VanTec seems to run at 4200 RPM max. What could cause that? Could the bios give wrong CPU fan RPM readings as well? (Maybe I should try counting them myself and see )

 

[Lord Evermore]

I think I pretty much explain why Abit's readings are so much higher here: http://forums.anandtech.com/messageview.cfm?catid=37&threadid=1060213&FTVAR_MSGDBTABLE=

Multiple threads about the same topic, just happened to post to that one.

The IC7 is a pretty nice board, but has quirks. The system fan connector is really hard to reach when it's in the case. Voltages can't be set to UNDER the default for the CPU installed (or possibly can't go any lower no matter what's installed, don't know), so you can't use lower voltage to underclock or simply reduce heat at stock speeds, which can usually do with a bit less voltage. The audio output doesn't work very well with the Cambridge Soundworks DTT2500, no way to make surround sound work properly, because they use a breakout box that requires digital input (and only has RCA or digital DIN) for 5.1 audio, and just floods everything to all channels, or disables the rear channels if you use analog and try to do 5.1. The IC7 has optical ports, which aren't much use for most people. And of course the IDE connectors are in the stupidest place ever.

The fans speed reading may simply not be perfectly accurate. If it's close to the rated speed, don't worry too much. Also make sure you didn't enable any sort of fan control in the BIOS. I don't think that the Aeroflow is temperature sensing, but if it is then it might be reducing speed due to that.

Paint one fan blade white, get a high-speed (100fps or so) camera and record it for a short time, then develop the film and see how many times the blade passes a certain point.

Abit boards are great o'cers. The IC7 should serve you well

Hello!

I just got my PC from a friend and I have a total of 3 cooling fans (1 from the PSU, 2 case fans), and the temp is around 50-55C for the CPU and around 47C for the motherboard... Is this still safe?

My specs are:
Motherboard: Asus
BIOS Version/Date: Award Software, Inc. ASUS P4S333-M /WOL ACPI BIOS Revision 1005, 3/5/2002
Graphics: GeForce FX 5500 128MB
1 DVD-RW
1 40GB Hard Drive
1 80GB Hard Drive
OS: Windows 7 Ultimate

Also, sometimes my PC gets stuck on the "Loading Windows" page, which is remedied by pressing the reset/restart button on my PC... I've replaced my fanner and so far, so good... I can keep the PC off for more than 12 hours and does not get stuck... I have a 500 watts PSU, will I need to consider getting a higher PSU?

@tates: Do you have an updated temperature limit site for Intel P4 2.4GHZ processors? Thanks!

Lol, isn't there a law against resurrecting 7 year old threads? I wouldn't hold your breath Lhon0901. But to answer your questions (in case this isn't a joke), those temps seem about right for that CPU, and no, you don't need more than 500W PSU. You probably don't need more than 250 or 300W.

 

[jjmIII]

Pull the Heatsink off and put new thermal paste. I'd re-install Windows just to make it mine.

Say, thanks for the replies... Heheh, I'm on a tight budget right now so I won't be upgrading anytime soon... Maybe a dual-core PC next year...

I just asked the question as there are times that the MOBO doesn't recognize either the second hard drive or the DVD-RW drive when I turn it on after leaving it off for more than 12 hours... So I guess I'm stuck to a single case fan as you said those temps are just about safe...

Thanks again guys! I'll try my very best not to resurrect this thread again...

 

[faxon]

lol by this time next year you can probably get a quad core cpu for $50 new with cooler from AMD

 

[Soulkeeper]

If that was a prescott core, those temperatures sound about right ...
those things were monsters, specially with the retail hsf
nothing can be done, unless your ears like 5000rpm fans

Really? Well, I'd rather have a noisy fan than a hot PC... My ears can stand the noise anyways... Just bought this system so that it can install Windows 7 ... I'll take all of you guys' advices and consider that as well when I upgrade my system in the future...

@faxon: I'd think about it, as I seem to like the i5 better...

Thanks for the advices again guys!
