Bios 3.5 and raised cpu temps

i just updated my bios to version 3.5 and my cpu temps went from 32c idle to 52 idle .now ive returned to bios 3.4 and my temps have gone back to 32c idle ..
has anyone else had this strange problem..i know the 3.5 bios updates the cpu microcode and maybe this is the problem or is it that the new bios is giving the right readings and the 3.4 bios giving the wrong readings.!!!!!!any help from the moderators is welcome on this subject

Bios reports 62 deg C cpu temp on XP2600/KT4A-V MB

Motherboard Monitor reports the same temp within a few degrees but the cpu doesn't seem very hot at all. This is happening on two similiar systems: same mb and cpu, 350W Antec power supply, 1 hard drive, 1 cd drive, and a 64mb GForce MX4000 AGP video card, 512mb memory.

1. HSF is installed correctly
2. I'm using a thin layer of Artic Silver.
3. One system has 2 sticks of Kingston 512mb and the other one has one stick of Micron 256mb.
But as I said in my original post, the cpus don't seem hot at all. I have another system with an MSI K7N2 Delta-ILSR mb/XP3000. The CPU temp on the XP3000 is 46 deg C and it is noticeably warmer in that I can feel significantly hotter air coming off the CPU. So I'm wondering if MSI is reporting higher temp readings on the KT4A-V mbs because maybe the sensor is on the dioide and not the socket.

Updated bios increased cpu temp?

I updated my bios from 1.7 to 2.1 and my cpu temp has went from an idle of 50 which isnt good anyways to an idle of 60. I flashed because when i went inot ht menu the bios would freeze and pc need manual reboot. Also theres alot of new options in the bios now anyone have a guide?

If you are overclocking, back down on the overclock to reduce the temps. What type of thermal transfer material are you using on the cpu heatsink? If too much is applied, it can restrict the thermal transfer.

CPU Temp and CPU Fan Speed

I am having a strange problem . One time I will boot the PC and CPU temp is 43 and CPU fan speed is 1308 rpm in Core Center. I do a restart system and the CPU temp is 32 to 36 and CPU fan speed 3308. Not sure if I should trust Core Center . Bios shows CPU temp 48 and fan speed of 3328. I have been reading here that there are a bunch of threads containing some kind of problem with CPU temp or fan speed. My Bios is 1.4. If anbody can give me some ideas that would be great.

Open CoreCenter on deshtop. Click where it says CoreCenter. Click Cool&Quite button. Then Click apply. This drops the fan speed back into the 1400 range and the temp will rise back to the 40s.

K8N Neo2 Plat cpu temp seems to be screw up...

Whenever I cold boot my system and when I went into the bios, my cpu temp will be like 40c while system at 28c then slowly raised to 34c which is reasonable. But cpu temp always around 40-42c not matter if I'm overclocking or not. I mean the cpu temp should be lower when cold boot and slowly raise depends on the room temperature right?
Sometimes it's screwed like cpu temp will reach up to 47c in bios and in windows when idle and when i reboot it's back to 40-42c using nvidia monitor and speedfan for readings.
Let's say when not overclocking, i set to auto for the vcore and it will shown as 1.35v. Even at 250HTT or more at 1.5v, in bios or windows, it's showing at 39-41c except for the load temp which i only see a difference.
It's just strange that cold boot cpu temp hit at 40-42c instantly and hardly moves even when vcore is at 1.5v in bios or in windows. Either that or it went up to 47c when idle sometimes but after a reboot, it went back to 40-42c again. I'm really confused why it's like this btw me using the stock cooler.

You took it right ! Is my english so bad...?? Bios ver. 1.5 shows correct readings after cold boot (yes when you are in windows and boot another time)
This 1.8 BIOS is not a Beta anymore. MSI will release this BIOS after their Holidays, many people in a german Forum are using it, without any problems!!
You should give it a try .... if you are experienced !!

Thanks MurdoK
I just flashed to bios v1.8 and the high temp of 40c when boot is fix
Now for cold boot, it's showing at 35-36c but the auto boot when psu switch is turned on showing blank screen with red/orange led light is not fix yet

K9N-Platinum wrong cpu temp + nforce drivers problem

I have a msi k9n-platinum (ms-7250)

Asus 7900 GT
6 x maxtor sata hd's

pioneer 110d
lg combo cdrw-dvd
When i builded the system , i installed Windows XP + Sp2 , made all windows updates
After i tryed to install the drivers a got wit the cd.
My system was very instable (i had no problem whit the motherboard i had before)
I made the install more than once , but still got instability
So i went to the nvidia site and downloaded the drivers for the chipset from there , and also made a bios update to v 1.2
System went stable.
Tried again after the bios update with the original cd --> not stable , randomless reboot
so i'm now working with the nvidia drivers from the nvidia site , it's stable but when i go to bios i see that the CPU temp is -38°
Is it a fix for this or do i have a wrong mobo ????

-38°C , seen that a few times now .
I think you should RMA/return the motherboard .
Why , see:

Not the same board as yours but all have a faulty calibraded (non workin) sensor on their motherboards .
The positive thing though is that the boards with this issue that runs on AMI bios doesn't freeze/halt as the award based ones does.

Can a bubble in thermal paste make CPU temp range 39ºC-60ºC?

Hello.
I've read the postits above and they say 45 ºC idle is very likely the heatsink spreader is not properly seated or the temperature is wrong.
But, what if idle temp is about 39 on the heatsink (meassured with a termometer) and the bios says CPU temp is 39? Does that mean I did well with thermal paste and heatsink? Does that mean the motherboard is reading the righ temperature?
It could look like I am asking a very easy question, but I feel it is not. Just go on reading.
I need to know if BIOS does actually provide the rigth temp because:
When the system heats up due to CPU under heavy load, CPU temp goes up to 50-55 ºC sometimes even close to 60 ºC. Could that mean there is an air bubble within the thermal paste but it is too small to interfere when cold enough (40ºC) but big enough when warm (50ºC) lowering heatsink performance and rising CPU temp up to 60 ºC?
Also sys temp is very high. It never gets below 50 ºC but I do not know where that sys temp is taken, and as I have the NB-fan connector conected to the power supply fan, I do not know what that sys temp means. :(
Room temp is around 25 ºC.
It does boot OS and I can actually play games (heavy load for graphics card and CPU). All readings I take were got from CoreCenter application at stock settings (Vcore 1.42 - FSB 201 - Mem volt 2.5 - AGP volt 1.5).
I am afraid of having done a nice job with thermal paste. I know (just read it here) I could easily fry the CPU if not, and I feel 55-60 ºC is too much, isn't it? Of course if BIOS readings are right.
BTW. Here follow details on the system:
CPU: AMD 64 3000+ NewCastle
CPU Family/Model/Step: 15.12.0
Thermal compound: Artic Silver 5
CPU Heatsink: Thermaltake Silent Boost K
Motherboard: MSI K8N Platinum
Motherboard BIOS: 1.4 (08/26/2004)
Graphics Card: Sapphire ATI Radeon 9800 SE AIW (not modded in any way)
Power Supply: Enermax 465 W [EG-465AX-VE(W)FMA]
Case: Lian Li PC-V1000
Mem, hdd, dvd-rw, floppy and D-bracket are present but did not feel necesary to provide details on them.
Thanks

Well, if your heatsink is cold and your CPU temp on BIOS is hot there are two possible reassons:
[list=1]
BIOS 1.4 does not guarantee accurate CPU temp readings
Heatsink is not properly seated on the CPU or thermal paste has bubbles within[/list=1]
But that is not my situation. I do know CPU readings are accurate when it shows 39 ºC because I actually used a termometer in contact with the heatsink to meassure it.
What I am not sure is if that accuracy is so when the CPU is hot (>50ºC) as it is when cold (

Z97 Gaming 7 Not Reading CPU Temps

I have had the Z97 Gaming 7 installed since July/2014 and had no issues. Today when I booted up I noticed that the debug LED was not displaying the CPU temp just "00". In the bios it also does not display the CPU temp but the system temp is displayed. In AIDA64 the CPU temp is stuck at 40c but it shows all the single core temps correctly.
I have removed the boards battery, cleared the CMOS and updated the BIOS to 1.80. Still showing "00" when booted up and no CPU temps in the BIOS. Can't understand whats going on here, could it be a dead sensor on the board? Some help would be appreciated.

Thanks Nichrome. Unfortunately here where I live, that is not an easy thing to do as there are not to many IT places i would trust to have this done. I guess I'll have to look around to see if I can borrow a Z97 board or a Haswell Processor to rule out with component needs to be RMA'd.
If any one else can add any more insight I would be grateful.

CPU temps/cooling?

So, I finally have gotten my system running, but to say it's unstable would be an understatement. It gives a BSOD on a regular basis. I've downloaded memtest, and it sees no errors in the RAM. I made sure to buy the tested and approved memory for my K8T Master2 FAR. I'm wondering if my CPUs are overheating. After the last BSOD, I went into the BIOS and looked over the temp readings. They were showing about 45 C. Now, this was in the BIOS after a brief cooling off from a memory dump. I wonder what the temp actually is under load. I can't get the system to stay up long enough to actually install the Core monitoring software. I took the side of the case off, and the CPU temps dropped immediately by about 5-6 degrees C (about 10 degrees Farenheit).
So what is a normal idle temp for these processors? Can anyone recommend a good hs/fan replacement for what came with the mobo? At the moment I'm pretty frustrated with the instability. I'm thinking it's heat related, since I've done several clean installs of the OS, with new RAM. I've swapped out vid cards, and disabled all the onboard hardware. It's more than a little annoying at this point. If anyone thinks the problem might be something other than heat, let me know. I'm powering the board with a 380 Watt Antec power supply.

Two thoughts about the temps.
First: with current BIOS'es (up to 1.3b5) and newer revisions of the opteron CPU's you will suffer from "Newcastle syndrome". BIOS and monitoring utilities will show temperatures that are way too high (I've heard 20 deg celsius). To check this feel the heatsink immediately after the system shuts down. If its not very hot than this may be your problem. Because of this the system may initiate shutdown if you have that option enabled in the BIOS. You should disable that option, or configure the shutdown temperature as high as it will accept. .
The system isn't initiating the shutdown. It simply crashes out to a memory error (IRQL, PFL, Thread Release). But about the power supply... I have a Raidmax 400W that I will try on it next. I was wondering if the PSU was sufficient.

Second: you describe that the temperature drops fast after opening the case. This could be an indication that airflow in the closed case is insufficient. Try running it with the case open for a while and check the temperatures. (not too long, because the cooling of other components may suffer..) If this is your problem the usual fixes are: check the directions of the case fans, remove cables out of the way, make sure th CPU fans are not obstructed.
Good luck.
As of yet, it hasn't crashed while running with the case open.... not that I recall anyway.

Mac Pro 2.66 (2006) CPU Temps

It's been a while since I took a look at the my temps and what not using Hardware Monitor but the other day I reached behind my Mac Pro... it seemed to me that it was awfully warm... so it peeked my curiosity...
Today I checked and my CPU temps are all around 135F... as I said, it's been a while since I looked but I seem to remember them being sub-100F at idle...
Am I not remembering correctly?
Thoughts?
Thanks!

See if installing SmcFanControl 2.2+ to create profiles and change default fan speed works, changes the fans.
Rather than wait for the system to heat up, switch to a higher rpm profile for that purpose, say 900-1000 rpm is still just barely audible but moves much more air and cooling. 1200-1500 for high.
Once the fans kick in, or cpus are under a work load, it can end up being cooler than it was.
The new 2009s with HT can be forced to use more power, create more heat. For 2006, the big issue is/was the ATI X1900 and clogging with dust and overheating, which needs to be pulled and cleaned every 3 months.

2 identical machines - different CPU temps

I recently built two XP3200+ identical machines (specs below). All parts were purchased from the same company (NewEgg) and both processors were retail packaged. My concern is the CPU temperature on System 2. Here are the vitals at idle with about 1 hour warmup:
System 1
CPU temp: 43 C
CPU Fan Speed: averages 3800 RPM
System temp: 38 C
System 2
CPU temp: 55 C
CPU Fan Speed: averages 4300 RPM
System temp: 38 C
I know both CPU temps are with allowable limits but why would they be so different?
BTW... I did try removing the heatsink, cleaning it and the CPU, then reapplying Arctic Silver 5 and got no difference in temperature readings. Anyone have any ideas?

I have a problem with this corecenter too. I buy a thermaltake cpu fan and my cpu tem. dropped about 40C . After that i think i updated corecenter.And i didn't looked so much to corecenter.One day i saw that in corecenter my cpu tem is about 50C. And that night i updated corecenter again and my cpu temp. dropped 42C from 52C
Which one i will trust 52C or 42C. I am frightening to hear don't trust both of them

2.7 GHz Intel Core i7 CPU TEMP 90c Too high?

Hi I have a mac mini (mid 2011) spec:
Processor 2.7 GHz Intel Core i7
Memory 8 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6630M 256 MB
Software Mac OS X Lion 10.7.2 (11C74)
22" + 17" monitors
and my CPU temp is around the 85c to 90c degree. Is this normal? Currently just surfing the net, and i think its making my mouse loss connections sometimes.
thanks for your help guys,

If you are in fact only surfing web and don't have a myriad
of background apps running, then 85 to 90C is in fact to
hot.
I have a new Mac Mini Server connected to a Thunderbolt
Display and have been surfing for a couple of hours and
have a CPU temp of 47C and fan at ~2300 RPM.
(Note: room temp is 21C)
If your Mini is running that hot, the fans should be roaring!
What is your fan speed?
BTW, the only time I hit temps like that is when I am using
Handbrake to do video conversions, which will max out all
cores available. The fan gets up to ~4500-4800 RPM.
The only time the Mini should get that hot is if you have
something running that will max out CPU usage. Check
activity monitor to see if there is some process that is
"running away" and forcing CPU to max out.
If the fan is not working properly, you may need to do
an SMC reset. If it is not working at all, get it fixed.
So, in conclusion, light CPU usage should not make the
Mini that hot!

2011 MBP 13-inch 2.3 GHz CPU Temp Issue

Hi everyone!
I am new both to the Apple forum and the Mac. Two days ago, I purchased my very first Mac--MBP 13-inch 2.3 GHz (not customized or anything). I've been playing around with the different applications and researching on different forums about CPU temp. In a quiet room, I can hear the low buzz/hum of the computer. I thought MBPs were pretty much silent? Sorry if this is a silly question, but I just want to make sure there's nothing wrong.
On average, CPU temp is around 49-55 degrees Celsius with the fan running just under 2000 RPM which is fine. When I tried recording my voice through the built-in mic on GarageBand, after about 10 minutes, I heard the fan go on full blast. I checked iStat Nano, and the CPU temp was 91 degrees Celsius with the fans running from 6200 - 7000 RPM. Is this normal? I had Firefox, TweetDeck, and iChat running in the background. Should I only have GarageBand open and nothing else in order for the CPU temp to not become as hot? 91 degrees Celsius is around 195 F so that scared me, and my computer was super hot combined with a really loud fan. Should I call Apple for support?
Thank you so much for your help, everyone!

I love Firefox, its the absolute greatest browser in the world I use it myself.
However Firefox and Chrome both are HUGE memory hogs, so you have to be a bit more conservative using them with other applicaiton's open. Occassionally in Firefox you may have to close all open windows and create a new one just to flush the RAM. Because everytime you open a new tab, it asks OS X for more memory and then doesn't give it back.
Also you must remember you bought a integrated graphics computer, meaning the CPU (processor) also does the graphics. This is double duty work the CPU must do and therefore twice the heat in one location.
There is a huge thread on these forums about the overheating 13" MacBook Pro's, perhaps if your a power user or a heavy multi-tasker that your should consider returning that machine complaining about the heat and get a 2.2 Ghz 15" MacBook Pro (or better) with the 1GB Radeon 6750M. It's a MUCH cooler machine and more powerful. I also advise the anti-glare high res screen so there are no reflections in the clasroom or at work etc.
I think you have a 14 day return window.

New bios 7.60 and temp. raise?

Flashed my K7N2-ILSR Delta the other day with the newest bios, and since that day my temps have raised with about 10 degrees celsisus. Right now I have a cpu-temp of 56, and when active it goes up to 60-65. This is not good, is there something wrong with the new bios giving false readings? The temp was fine before and and all fans etc still work.
Thanks!

Don't worry about it...it's a bad reading from the BIOS...there's a lot of discussion among everyone about the temps...
Get a Temp Sensor and mount it under your processor...that's the best way to know what it's really doing...

3.9 Bios and CPU temp

I have just installed the new 3.9 bios and have noted the cpu temp was sitting on 50c. It is normaly on about 40c when running at 1730mhz. I dropped it back to 1530mhz and its made very little difference. Anyone else noticed this.
