Optimummind

I finally shelled out some major cash and went on a shopping spree. During the last 3 days, I got a new mobo (exchanged at Fry's for a Soyo 865PE Plus Dragon 2), a TDK DVD+/-RW, a new PSU (Vantec 420W), and the Koolance Exos Watercooling kit.

The BIOS of the Soyo 865PE mobo detects my CPU tempeature at 45 degrees celcius at idle. Funny thing, though, is that the temp always stays the same whether I run benchmarks/programs or not. I've looked on the Internet and it seems like everyone is having the same issue and is waiting for a BIOS update for the CPU temp sensor.

Even more funny is that Sandra Pro 2003 will detect the CPU temp at 75 degrees Celcius. Once again, the detected temp will not change at all.

With the Koolance Exos kit, however, I think I found the real temperature. The kit comes with a CPU temp sensor diode that attaches to the bottom of the copper waterblock. At idle, I get a reading of 28 degrees Celcius (overclocked to 2.61GHz from 2.40GHz) and on a full load, I get 32-33 degrees Celcius!! I should've gone watercooling before!

For comparisons sake, I used to get CPU temperatures of 45 to 49 degrees Celcius (overclocked to teh same 2.61GHz speed from 2.4GHz) when I used to have a MSI 845PE Max2 mobo with an Aerocool copper HSF rated to cool up to 3.6GHz speeds.

normally the cpu fan speed is determined by temp. if you have an adapter, try plugging the fan into that spare 4pin connector from your ps. this will cause the fan to spin at full speed all the time. then wait a day or so for your compound to 'set'. then stress your cpu & see what you are getting for temp.
bty, where are you getting you temps from? bios or some program?

BASTARD!!
how much was the kit? though my 2.4 does not want to go above 3.1 so do not know if it would be a good investment. got it at 3.03 & still at my self imposed 50c limitation. guess i can not complain.

might try that adaptor bit.

but after all that could it be just as Optimummind as said in his post i have abit is7-e springdale that uses the 865pe chipset Oswell.because personally the performance i am happy with no sudden shutdowns or anything of the sort.

might also consider a Thermalright SLK-900U (Socket 478 & Socket A) (HS-008-TR)
heatsink with a 80mm fan.at some point.

i am using same chipset on asus p4p800. well, if you are happy, cool. that is still a very high temp, especially, if i understand you correctly, that is you norm temp. which means you have a problem.
you are getting that temp from the bios right? & the heatsink is firmly seated & the surfaces are completley free of all oils,specs etc.?
also, have you checked your case fans to make sure they are performing & is your ps fan working like it is supposed to?
given that your case temp is reasonable, it pretty much puts it on the heatsink/fan. have you visually checked the fan to make sue it is running? i know you got a rpm reading, but just in case...
you also might want to consider calling cutomer support or intel(web) for wherever you got that cpu.
unless you are going to overclock there is no reason to get a different fan. those stock intel fans do (normally) a very good job & usually give you some good overcloking headroom just by themselves.

bear in mind i only installed everything a week ago.i do honestly think the fan on the hs should big greater than 2100 rpm at this time.some of the other h/s i have seen online look like they are using 80mm fans and are much deeper in depth due mine looks around 70mm & only around 10mm in depth.

do you think that could be a possibility for reason.there is not much change in temp straight after load either.

all readings are from bios & hardware moniter.all fans are running and hs is seated ok due to clips in each corner.

i agree about the rpm, that is why i suggested the other hookup.
believe it or not, the intel stock setup is actually a good heatsink/fan combo. there are not that many out there that are going to give you better performance per cost.
i still would like to know were you get your temp from. if you are getting it from some sort of program the ycan be off by as much as 10c. your bios is your best bet.

just saw your edit. turn your comp of & go into your bios & see what it says. then, ass soon as you boot up check your prog & compare.

please forgive this question, but i have seen it happen. you scrapped that crap of both cpu & heatsink before you put that paste on? & really cleaned both?

__________________

MIG-31

yep just curious what is the best stuff to clean them with. plus bios reading is the same.

how much would hyper-threading make to temps.

also going to pick up a adaptor tomorrow

alcohol is cheap & easy. just do not use someting like a cotton swab that can leave filaments. sponge sticks(like for tape head cleaning work well). i you have a good electronics store something like blue shower(my choice)or any other electronic cleaner spray would work great.
bios agrees huh? bummer. i was really hoping that was it.
ht has little to no effect on temp.

appreciate what your telling me now stuck on what to do?appart from try new h/s.

get the adapter, reclean & paste cpu, make sure heatsink is firmly & evenly installled, attach that adapter, check ALL fans, & let it run for a day or 2 to let the paste 'set'. then check your temp under load. let us know what happens & we will go from there.

The kit that I bought came with a CPU cooler block (unlike Internet purchases). After taxes, the whole thing cost me $246.00. The only thing extra I had to buy to set my rig up was a medium-sized wire cutter.

mike2h

thx for info.
considering i had to wine to get my mcx 4000, with my wife asking me what was wrong with the perfectly good cooler(she had a point) that came with it, i think i would be dealt serious bodily injury if i brought that up.

when are you going to run your clock up? i am REALLY curious to see how high you can get that. seems like most of these p4c are topping out around 3.4 with realistic cooling & being able to use it all the time.
anyway let me know what you get.

Since my 2.4GHZ 533FSB CPU didn't die together with the mobo, I was only able to get the mobo exchanged. On the positive side, all of my other components survived too (9800 Pro, HDDs, RAM).

I noticed that my northbridge chipset can get very hot if I overclock beyond 2.7GHZ. So, until my Swifttech MCX-159 Northbridge cooler (5200 RPM, 6.4CFM, 18dBA) arrives, I won't be doing any overclocks beyond 2.6GHz. It's also unfortunate that the DDR:CPU ratio funcion seems to be not working properly. I hope Soyo fixes that soon with a BIOS update.

Here is the pic of the Swiftech MCX-159 NB cooler.

is right! was it a fairly easy install? mainly i was wondering about removal of stock northbridge heatsink.
do you have an estimate ofwhat your pre & post northbridge temps are?
that would look really cool siiting on my mb next to my mcx4000. be kinda like dr evil & mineme, or batman & robin or....

hope they do fix your bios issue soon. got to wonder about qa on that one.
you know you can pick up a 2.4c for about $170. you should be able to find some suc.. er, i mean someBODY who will by your current cpu.

it is a start. hopefully running that fan at 100% all the time will give you another couple of degrees. still think you ought to reinstall that cooler.

here is a good guide from our very own wyrethewolf, this is in the oc/mod section if you have not already seen it :-


Well, I have been asked a few times what is the easiest, best way to apply thermal grease to a heatsink. So I have decided to write up a quick guide on exactly that subject.

I don’t know if this is the best, or the fastest way to do it. But, this is the way that I do it... and it works just fine for me.

Now the idea is to get the thinnest, most even layer of thermal compound only where the CPU core will contact the HSF. This will give you the best possible heat transfer from the core to the heatsink.

You will need the following:

-heat sink
-thermal compound
-clear (thin) tape - and test to make sure the tape doesn’t leave anything behind.
-Straight edge (I use a razor blade, be careful)



First step is to tape off the area where the CPU core will be contacting the HSF. If you are not sure where the CPU will contact the HSF, you can put a small amount off thermal compound on the CPU core, and do a test fit. That will give you an imprint of the CPU core on the HSF, and show you where you need to mask the HSF.



Next, place a small bead of the thermal compound into the middle of the taped off area.



Next, using the straight edge (razor blade) smear the thermal compound around until it fills the taped off area.



Lastly, remove the tape... And there you have it. A perfectly even, and thin layer of thermal compound. Exactly where it is needed.



Good luck!

I haven't received the part yet from FrozenCPU.com. But, since I ordered it through their 3-day UPS shipping, I'll probably get it either tomorrow or Monday (unless UPS does Sunday shipping). The cool thing about the MCX-159 is that it can be attached to their mobo in two different ways. One, through the holes near the NB chipset (which would require partial mobo removal), and two, by using the latches that hook on to the mobo (I prefer this way).

By the look of it, the installation seems like it'll be simple. I'll be sure to let you guys know once I get my hands on that sweet-looking thing.

Duranix

amd athlon XP 2400+ @ 2227mhz (default 2000mhz)


i get around 25C idle, and about 32C under load.

Zelig

Barton 2800+ @ 2255 mhz up from 2080 mhz. (12x200mhz)
About 25 idle and 35 under load.

Currently, my heatsink is easily the loudest fan in my rig, at about 25 dB... I won't be doing anything to it, but next time I get a new mobo/cpu, I'm trying for something quiter.

Oh ya and this is on a 3GHZ Northwood with HT oced to a little 3.3GHZ.

Still, 18 degrees! A big gap

Sandok what program are you using to get your temps? Or are you using a multi-meter?

I'm using Asus Probe.

The thing is, my CPU fan spins at 2500ish RPM and if I make it go up to 4800 RPM, the idle goes down to 34 and the load goes to 44 making only a 10 degree rise which is still alot but then my ears die

TJ-

i to got asus probe---

cpu at full load (100%) for over 2 hrs is 48 right now, uasally sits at 43-44.

mb right now is 40, and thats what it uasally sits at.

The most my cpu has been is just above 70, which is pretty high...
mb almost always stays the same at about 40-45

Wow, OLD THREAD! Maybe start a new one???

Highest I ever see is 43c .... Idle is around 33c to 37c depending on room temp. I have an 80mm adjustable thermaltake blue led light fan on the Thermalright SLK900A Running at about 3900RPM....
