I assembled my first computer 2 days ago, and i think it is running a bit hot.

CPU - Intel Pentium Dual-Core E5200
HSF - Scythe Katana II
Motherboard - Gigabyte EP45-UD3L

It was running at about 40C (60C to TJMax) idle and 58C (42C to TJMax) under Prime95.

I then reapplied the thermal compound so it was not as thick, and resat the HSF, it now runs at 38C (62 to TJMax) idle and 51C (49C to TJMax) under Prime95.

It is running at 2.5ghz (200 x 12.5) with 1.225V VCore, and ambient temperature is 25 ~ 28C, the usual being around 27C.

The readings are from RealTemp with the TJMax untouched at 100C, and the motherboard BIOS reports the CPU temperature to be around 26 ~ 28C.

So which temperature should I trust? The BIOS temperature, or the temperature from RealTemp?
Or should I try to calibrate my temperatures according to this guide?

PS: I am using the Cooler Master Elite 330 case.

Your case doesn't have great cooling if I recall... see if you can add another fan to the side panel, and make sure the rear fan is actually exhausting.

oh yeah, all you need is a small line or dot in the middle of the processor, and your heatsink will spread it by itself

remember: less is more when it comes to thermal paste.

what CPU cooler r u using??

im using HWmonitor for my temps and voltages. it seems accurate and matches BIOS etc. the temps in BIOS are not the actual core temps. HWmonitor will give u the CPU temp and an internal temperature for each core.

temps on my E5200 are 28*C idle and 40*C load w/ my Xigmatek Dark Knight with AS5.

(by the way 250x12.5 is not 2.5.... its 3,125 mhz.... stock speed is 200x12.5- 2.5ghz for the E5200)
(and that url u linked seems to be for quad core CPUs, not dual... get HWmonitor and see what those temps are)

Oh, my bad, I meant to type 200 x 12.5, not 250 x 12.5.
With HWMonitor, I get 39C Idle and 52C under small FFTs in Prime.
The cooler im currently using is the Scythe Katana II.
While I'm at it, I should ask this: how much thermal grease is good? And does it really spread if I just left it there?

The temperature reading that the BIOS and several temp programs reports as "CPU temp" is the temperature of either the IHS (Internal Heat Spreader, the metal soldered to the CPU) or the socket the CPU is in. Think of this temp more like a general temperature of your chip.

The temperature reading you need to concern yourself with is the "core temp". Realtemp also outputs a "distance to TJMax" this is essentially the distance to thermal throttling, and cannot be altered by changing the TJMax settings value. The TJMax value that you can change in RealTemp is only changing the temperature's it is outputting. The distance to TJMax reading is raw data straight from the processor, and is not even a temperature reading.

What realtemp and coretemp etc try to do is take non-temperature data and turn it into a temperature reading with a formula. Just keep your distance to TJMax above about 30 (which you are so far
) and you should be fine

I tried reapplying the thermal paste 3 times, ended up with higher temperatures, so I decided to apply about the same amount as i did before, and it is the same temperature now.

Oh well, thanks for your help guys

@tbates1244

Yeah, that's what I thought when I read stuff over the internet, but I was a bit concerned since a lot of people say that they can idle in the low 20C's and go up to around only 40C-ish under load

u should be using about a pea-sized dot (or even a bit smaller) in the center of the chip.

make sure u screw down the mount till the screws wont turn anymore, but dont force it. it will stop where it needs to. the paste will spread very well.

what paste are you using?

----
i looked at ur CPU cooler and its not a HDT (heatpipe direct touch) cooler, so the single dot in the center should work fine, then tighten the screws till they wont turn anymore.

i cant see why ur temps are so high.... try taking the door off your case and getting air in there, then make sure its exhausting hot air out of the case properly.

if none of this works, u might have a defective chip. the internal HS might not have been soldered on properly, or something of the like. also ur mobo might not be reading temps properly due to some problem w/ the board or the socket...

extended periods at high temps are dengerous. your temps are not dangerous as of now for ur chip, but i would solve this ASAP cause ur cutting time off the lifespan of the chip with every hour that it spends at above-normal temps.

I'm using the paste that came with the cooler, I'll try to get some better paste from a friend soon (I live too far away from a computer store).

If i take off both covers on my case, and open the window, the ambient temperature drops from 26 ~ 27C to 23C, and RealTemp will read 34C-ish for the idle temp

thats a bit too high...

get some better paste if u can... cant imagine it making THAT big of a difference. either something is going majorly wrong when ur seating the CPU, ur getting erros with the temps, or u might have defective hardware.

yes, depending on the paste, u can see ~3*C to ~5*C temp drop.

my idle is 28*C, load during games is 40*C. those are cpu temps. my real internal core temps during games are 50*C max.

this is from another post i made to help a guy find a CPU cooler. read it and look at that guide. its got other pages for several different types of coolers. the earlier pages are for normal HSFs instead of teh HDT (heatpipe direct touch) coolers

id like to see ur temps compared to mine w/ AS5.

look at this great guide when mounting ur Dark Knight. i filled in the grooves like they did in that guide. then i used the method with the two 1cm lines on the cooler to mount my CPU. i didnt lap my cooler like they did, even though the HDT coolers have a less-then-perfect base. i used a plastic card, like a credit card to push paste into the grooves, tehn wipe off extra w/ paper towel. then repeat till the channels are filled to your satisfaction. that is still a great guide.
according to this 33-way Thermal Paste comparison, OCZ Freeze is the best overal thermal compound, by a small margin though.

Ok, so I played around with the BIOS a bit
Now running at:
RAM: 4-4-4-12 570mhz (1:1)
CPU: 2565mhz (285 x 9)
VCore: 1.09375V

Resat the HSF again, following the guide, place HSF at an angle, twist for removing air bubbles.

Now under Prime95 Small FFTs, I get 49C max, and it is fluctuating between 48 and 49C. Again, the ambient (room) temperature is 27C, so i guess this is ok now, a difference of 22C between ambient and 100% load.

those voltages are a bit high 1.225 I have mine at stock cooler at 1.1 at 3.0 and it has 55c

Sorry didnt read all the threads. I had mine at stock running 1.08. Try seeing how low you can go. Nice psu wattage you got there. Sounds just like mine 350 watt. I have its cousin or sister or what ever because I have the ud3r

for some reason, my chip can't POST at 3.0ghz (240 x 12.5) no matter what.
And I want to use a FSB setting that's less than 290, cuz anything above that, and I can't use 4-4-4-12 timings.

Temperatures are getting better now that i resat my HSF, I think I'll do it again cuz I didn't lift it to check for air bubbles last time (the time before that, a HUGE chunk of grease wasn't even touched by the HSF base). It is at 57C max under Prime95 Small FFTs, and fluctuating between 55C and 56C usually at 3125mhz (250 x 12.5) @1.24375V.

who are you talking to? me or the other guy? didnt know what numbers ur talking about... lol

to kira:

i havent run prime95, my "load" temps are just my max temps while gaming. i didnt want to mislead u. ur temps in prime will be higher than what i said my load temps were cause prime is more challenging than games.

i have mine at 266x12.5=3.33 ghz @ 1.28v Vcore

Ah, I see, that makes sense.
I did a (FSB x 6) test earlier today, the most it'll boot at is 311 x 6, which can give me almost 3.9ghz if i want to reach that.
Since there's about a 55% headroom on this thing, I though I might want to OC it, but I guess I really do not have a need to as it runs fast enough at stock for me, and to add to that, it runs pretty hot.

Can you please tell me what games you are playing so I can get an idea of my processor's thermal performance? Thanks in advance.

On another note, I wish my room temperature would go below 23C, 27C is a killer to stay in.
