Two distinctive questions, merged 1 thread! tldr at bottom
System Specs if relevant:
+ Show Spoiler +Athlon II X3 3.2ghz unlocked to x4
Biostar a770e3
NZXT Gamma Case
Single Top Rear Fan
1: All of my CPU temperatures are incorrect. Coretemp, HWMonitor, various system monitors, Speedfan, AMD OverDrive, all say my Core temps are about 15*C during general web browsing/idle, and hitting about 55*C max during prime95 running for a short period of time. Now, my ambient temperature is 26.8*C - so these readings must be impossible.
In Bios, I found that my CPU temp is generally 32 to 36, generally it stays at 36 and only starts at 32. I assume bios takes more load than general web browsing, because that's a 4*C difference from min to max, whereas CoreTemp usually shows pretty low temps when just browsing. This is a 20*C difference! (I imagine my system failed on the 23rd hour of prime95, so late, because it was just barely overheating the whole tme).
Also, System Temp reads about 26-27, which is what TMPIN1 and TMPIN2 read. Since System temp is probably sensor temp, maybe I should rely on a sensor temp and then offset about 10*C? Anyways, I was wondering if offsetting CoreTemp or some other program would be an accurate (as far as software) reading of my temps. There's a big difference between 55*C in Prime95 and being like "wow my system is cold!" to 75*C which is HOLY SHIT TURN IT OFF! This actually means my system at stock is too hot!
fyi, I know when you unlock 4th core temp readings are supposedly inaccurate, but I've done this both with and without unlock. Same 16*C readings.
2. I have about $20-35 to spend on my PC. I'm thinking cooling for some minor overclocks and since I only have a single exhaust fan. With that said, where should this money go? I was originally planning on getting 4 Yate Loons from Petras, but I may be better served simply getting a single Hyper 212 Plus. I just wasn't able to find anything out there about the temp drop additional fans do, while I read the Hyper is about a 10-15*C drop. There's also the issue I only have 2 more peripheral molex so I have to get a sata adapter or y splitter :X
TLDR
Two questions:
1. All cpu temp reading programs say 16*C. That's impossible, but Bios says 36*C, which seems more believable. Are offsets reliable, or is there a way to get a program to report my Bios sensor reading?
2. I have about $30 to spend on cooling (atm stock hsf and single rear exhaust). what to buy, and how much cooling do additional 120mm do?
|
hyper 212 and mabe the programs dont work well with the athlon x3 ...16 does seem way low unless your in a freezing cold room
|
No, I'm comfortably warm.
On Toms Hardware this $19 fan was rated the best fan for under $40, Nov 2010. Problem is it isn't compared to the Hyper, and I can't really find any comparisons online yet.

It's not just Coretemp though, it's every program that says the same 16*C or so. They all rise and fall exactly the same, when I run a few programs and hit say 26*C, they all say 26*C. When I'm idling, they all say the same 12-18*C.

Update your BIOS first, also I think a lot of AMD chips can report incorrectly if unlocked.
|
|
|
Yeah if you unlock extra cores you can't rely on the CPU sensors at all.
|
So I ran prime95 for 5 minutes and temps were at this:
CPU Temp in all programs: 55
CPU w/+20 offest: 75
Speedfan:
Temp1: 61
Temp2: 39
Temp3: 27
I restarted and ran to bios as fast as possible, and temps read as:
CPU: 45
Sys: 27
It looks like nothing is scaling correctly ;/
I just need a CPU Temp monitor that follows what the Bios CPU temp says. I have no idea where the coretemp/general CPU temp comes from, I mean 16*C is just not right, can't be any possible sensor on the board saying that.
|
HWMonitor should show it under ACPI temperatures.
|
I can definately advocate the CM hyper 212+, I run a 965be @ 3.8ghz and my max temps after 12 hours of prime95 was 50c with the hyper 212+ with ambient temp of around 22c. Max temp with the stock heatsink at 3.4ghz(stock clock) was 56c.
Does your case have any space for an intake fan? With only a single 120mm exhaust your case temp will build up over time unless you take the side panel off or add another fan.
|
Yep. I may just go for 2 x Petra Yate Loons and a Hyper 212. A bit over budget but apparently worth it. I think the best way to put the fans would be 1 front bottom intake, 1 top rear exhaust (and then theres my stock rear top exhaust). I hear side intake fans reduce temps as well, so I may go for a 3rd, or make the 2nd a side intake instead.
R1CH none of the temps are listed as ACP1 but I think your talking about the THRM/TMPIN0-2 temps, which are all 20*C or 26*C when idling.

Specs:
+ Show Spoiler +Athlon II x3 (unlocked x4) 450 3.2ghz
Biostar A770E3
2x2gb Kingston HyperX 1333
GTX 460
Stock HSF
NZXT Gamma case (single stock 120 mm top rear fan, bottom PSU, many empty fan mounts and holes/ventilation)
My temperatures in Coretemp are always around 15*C idle, with lows up to 12*C at times. It is usually about 16*C with general web browsing, and maybe up to low 30s during long periosd of gaming. However, this is impossible - ambient temperature is a comfortable ~75*f, or 27*C. I know supposedly unlocking a 4th core can cause incorrect reads, but this is the exact temps with both unlock and stock.
And it's not just Coretemp - every program reads the same ~16*C. Speedfan, HWMonitor, AOD, and more.
In HWMonitor, there are TMPIN0 and TMPIN1 and TMPIN2 - I assume some sort of socket temps. TMPIN1 seems to follow my System temperature in bios at about 27*C.
Now, in Bios, my CPU temperature reads at about 36*C, maybe down to 32*C when first entering BIOS. This seems more accurate.
When running prime95 for about 10 minutes, Coretemp goes up to 55*C - which I initially thought meant my system was cool runnings. However, with a 20*C offset (making the 16*C idle to a more normal 36*C offset that seems to reflect bios) this means 75*C! You can see where my concern comes from...
I'm really not sure what to do. There's no way to really tell if Coretemp is even scaling correctly, as I believe Bios Health monitor will shut my PC down at 65*C, well below when my Coretemp+20 offset is reading 75*C. And temps usually get back to 40's within a minute or two of turning Prime95 off, so I can't really just run prime95, and then run to Bios as fast as I can.
Help! I can't even begin doing any sort of minor oc'ing if there's a possibility my system is going to 75*C at stock, and I have no idea if it's worth getting a HSF or additional cooling fans if my system is running just fine, or extremely hot.
My system seems cool off very quickly, despite only a single exhaust. The NZXT Gamma has a lot of holes and stuff. http://www.bcchardware.com/gallery/albums/NZXTGamma/SideProfile.sized.jpg
Front is all like meshed metal, no blocking of air intake.

Hm, actually 75*F is more like 24*C. So TMPIN1 is the only 'physically possible' temp at 28*C in general usage (HWMonitor, Temp2 in Speedfan. It heats up to about 32*C when I slow my CPU fan down to 60% (which is the general bios temp!) but 28*C is still generally lower that what bios says.
Still, this must be a socket temp? Is this a safe temp to go by for temps?
THRM and TMPIN1, Speedfan Temp1, go to 55 in about 5 minutes with prime95 on. However on idle, these temps are all about 20*C. Way lower than the Bios' 32-36, and even if my room is at 73*F=23*C. That actually rises pretty similarly to Coretemp.
I'll investigate these temps further!
******************************
On another note, I bought a Hyper 212 plus and 4 x Yate Loon Mediums (PTS offered 4 x for $20 and my roommate is getting one off me). The rationale is that $30+20=50 spent on cooling and doing minor overclocks on both CPU, GPU, and CPU-NB will net a better performance boost than a $50 more expensive processor than my $79 Athlon II x3 (which isn't really accurate since I got lucky and unlocked a 4th core - unless it oc's horribly). Basically, I could've bought Athlon ii x3 3.2ghz and cooling, or a Phenom 3.2ghz x4 BE. Same clock speed, but it's basically either high cooling vs l3 cache. Given that l3 cache also gets pretty hot, I'm banking that I made a smart buy, as I'll be able to do great overclocks without getting too hot or changing the voltage.
As for BE, that's stupid. Even though I don't have any experience (just oc'ing droids and lots lots lots of reading, im now a member of every oc forum around lol), because of locked multiplier all that means is that I'll just have to lower the RAM, CPUNB, and HT Link Speed to keep up with reference clock going up, which you'd have to do with BE eventually to get the most out of your system.

actually 75*F is more like 24*C. So TMPIN1 is the only 'physically possible' temp at 28*C in general usage (HWMonitor, Temp2 in Speedfan. It heats up to about 32*C when I slow my CPU fan down to 60% (which is the general bios temp!) but 28*C is still generally lower that what bios says.
THRM/TMPIN0 seem to be likely to be my CPU temp - when I run prime95, these shoot up just like my clearly impossible CPU temps do. They idle at about 20*C, and have a high of 58*C, which seems right on. However, a low of 16*C it too low. Unlike my CPU temp which has a low of 10*C (wow! usually about 14 but left my PC on for a while now) and hovers at 16*C, THRM/TMPIN0 have a low of 16*C but usually hover at 20*C.
TMPIN1 seems also very likely to be my CPU temp - it hovers at 26*C, has a low of a very possible 24*C, but the problem is that the max value is 41*C, which may be too optimistic. Similiarly, I've seen Bios temps of 44 when I reset my pc really fast to see what it'd be from heat from prime95.
I just wish there was a program that could read the Bios-Core temp reading. My Bios CPU temperature had a much different rating than any software program (none of my temperatures are ever idling in the 30's while my CPU in bios always is) and I really think that may be the correct temperature, but I have no idea how to monitor that. I can't exactly run prime95 and do benchmarking in Bios.
|
If I can't monitor temperatures, then I won't know where to add my 3 Yate Loons coming in tommorow 
I know 1 should be intake, but I don't know if I should put the other 2 - top exhaust (yate loon is sleeve bearing, so i'd actually make it a rear top exhaust and then take my nzxt stock rifle bearing and place it on top), side intake, side exhaust, lower side exhaust, or as a 2nd HSF for push/pull on hyper212.

temperature can drop in a matter of seconds on a CPU so by the time you shut the pc to going into the bios, if the temp was really high, it coulda dropped around 20C in that time.
When i oced my X2 phenom, i got no readings from the temp guage so what rich said is true, u cant really rely on cpu temps when ocing or unlocking cores.
I would suggest you get a liquid coolher like the H50 or H70, not too expensive but will do a better then air job of cooling

I should just buy a Phenom II. Actually, that's stupid. I should just buy an i5 - wait, make that an i7. While I'm at it, get liquid cooling. No, that's dumb, get liquid nitrogen. This can go on and on. My system at stock is complete overkill for anything I want to do - play Starcraft (gtx460+athlonx3 3.2ghz 60+fps on extreme). I merely want to do a bit of oc'ing for fun, was willing to get a hyper 212 and a few extra fans but that's it.
And the problem is that my temps are so whacked out, I have no clue what they really read. This could be a big problem when I try to run prime95 for stability testing, as according to my Core readings with 20*C offset I'm overheating at stock. I also have reason to believe that may actually be happening, since prime95 at the 23rd hour shut down, I'm not sure why but my guess is that the CPU was just barely overheating the entire time, so it didn't shut down immediately but instead 23 hours later. There were no errors reported by prime95 either.
So the idea of just ignoring my CPU temps, and then getting a liquid cooler, doesn't sit well with me. I imagine a liquid cooler is complete overkill too, especially if I'm not doing major overvolts.

loving the sarcasm  well as for prime95, if im not mistaken most if not all CPUS have a temperature cut off level that once the cpu reaches that temp, the computer shuts down or something.
One way of testing if your cpu overheats too much, leave prime95 running for a few hours (or run IntelBurnTest for 10-20 mins  ) and if your computer hasnt restarted, ull no that at its most stressed, the cpu hasnt overheated

If all my sensors are wrong, how will it know when to cut off?
Bios may be the most correct, and it has a shut off at 65*C. But I'm surprised not a single program reads the same temp that BIOS does. TMPIN0 seems to be most correct, and spikes when CPU usage goes up, but it does sometimes fall below possible temps by 2-4*C. But nothing spikes as much as Coretemp, which makes me wonder where exactly is that reading from. I may just be able to use a offset, but then its a matter of how much. TMPIN1 also seems pretty likely, being the only possible temp, but it doesnt spike nearly as much. I'm pretty sure that's my system temp. Everest says its my motherboard temp. TMPIN2 is labeled as CPU temp in everest (read: not core) but that doesn't really go up much.
|
well i guess you could just get the highest temp sensor and use that as current temp. that way your always looking at the worst case (unless the highest temp sensor is lower then the current cpu temp o.O)
the only other thing i can think of is an external thermal sensor
|
lol I like how you're getting more responses on a sc2 forum than on the multiple tech forums you posted this on (seems you're the only one with this issue on google).
