Oc Temps

k, i finally took the plunge today and oced my pc.

i have a p4 2GHz - as standard, fsb=100, multiplier=20

very first oc went amazingly - upped the fsb from 100 to 101, no problems to report - all ran smooth @ 2020MHz! ;)

then i went for a couple of increases and tried 2100MHz (fsb=105). booted fine, so i decided to run a test, I ran prime95 "torture test" to max out cpu and ram for a couple of hours, whilst monitoring my temps.

Under full load, i ended up at 50C CPU; after the test, it dropped pretty damn quickly to 40C. now i cant remember what this was before the oc, but do they seem reasonable, or should i be thinking about sorting out the airflow etc before going much further? asus probe has the default critical temp of 60C - does this seem a reasonable level to stick under?

50 degC is hardly a fatal temp, but of course you would like it to be lower.

Maybe you can load MBM5 and keep an eye on some critcal temps (chip, board and HDD, for instance) while using your machine normally...after all, unless you are folding, it's not likely that you'll be running your chip at 100% all the time.

In a perfect world, I like to see full load temps in the 35-37 deg. range, but this is not always practical ( or achievable ), and I am probably overly compulsive about temps anyway.

It would be nice if you could knock a few degrees off though....

so clocker, what are your current load temps at? are they actually in the 30's?

Yes.

Running at 100% (Folding), right now I'm at 34 deg.C.

:o

those temps are amasing. what aare your idle temps?

btw, does anybody know what a good temp for a celeron 633mhz is? my friends is 27c idle and i want to OC it but he wont let me because he thinks that temp is high <_<

Idle is around 30C, but I&#39;m rarely idling....

holy crap - i just put mine back to standard 2000mhz to do some testing and playing, and im running 40C idle and ~48C using Prime95...

i gotta buy a nice big fan, then im off ocing again :)

I&#39;ve noticed a recent spike in my temps where as they used to be 41*c idle they&#39;re now 45*c.. I&#39;d put it down to the weather but I live in England it&#39;s hardy hot at the best of times :rolleyes:

Holy Crap&#33; I&#39;m starting to get worried now, just checked my BIOS and my CPU temp is 66°C, and I haven&#39;t even OC&#39;d it :unsure:

I have a Matsonic MS8147C+ Mobo with a Barton Athlon XP2500 chipset. I have two case fans (one at the back and a neon one on the window of the case) and according to my GFX card the ambient temp is 33°C.

Are these temps too high? and if so what do you all recommend to cool it?

those temps are veyr high, id hate to see ur load temp :unsure:

Have you ever removed your heatsync from your cpu? if so then you should have bought some arctic silver 5 to put on, a thermal pad can only be used once, after the heatsync is removed it is ruined and you need a new one.

either way i recomend you make sure ur case has good airflow (neat and tidy) and that all your fans are working, if thats all ok and the temps are still high then i recomend you buy some arctic silver 5 to apply to your heatsync.

instructions for applying arctic silver 5 are found HERE&#33;

Ouch&#33; that is really hot did you build the pc yourself?

Thx Rossco, I&#39;ve never taken my heatsink off (bought it as a motherboard bundle from Novatech.co.uk)

That instruction guide looked a little advanced for me (I am a hardware spaz :blink: ) Would it be easier for me to add a better cpu fan?

And should my case fans blow in or out? Or should I have one set up as an exhaust?

a new cpu fan wont help much, a new heatsync on the other hand would probably help temps a little, but if ur gonna try that then u might as well do teh arctic silver 5...its not hard, u just take teh old stuff off, then apply a bit of the new stuff and put teh heatsync on...

where are all ur case fans setup in ur pc? the back one and top ones should be set as exhaust, and front&#092;bottom ones should be set as intake. and you could try the side panel one, if u have one, both ways to see what gives better temps...

I have the back and the top as exhaust (also the side panel is exhaust), I&#39;ve just nicked another case fan of me mate and I&#39;m going to set that up as intake at the front. He seems to think that the CPU fan and heatsink are either the wrong type or were badly installed or that the temp sensor is faulty. Either way I&#39;m going to get a new heatsink and fan and try that Silver 5. Will keep you informed, Thanks :D

alright that all sounds good. try the side panel one both ways, most people have gotten better temps with it as an intake becuase usually its lined up perfectly so the air from teh fan goes right ontop the heatsync...

Here is a tip a lot of ppl forget

over time all that cool air thats blowing on you cpu heatsink also builds up a lot of dust and crap in the fins of the heatsink

i have see heatsinks where the fins where blocked by crap , this was on a comp that was not even a year old

ocasionaly remove the fan unit from the heatsink and clean out the fins, you would be suprised how that will drop your temps down

Okay, Just moved my case fans around a bit (2 exhausts at the back, 1 intake at the side - cant get a fan in the front because of the case lights&#33;) And there dosen&#39;t seem to be much change in temperature:

I think Delphin is right because it was pretty filthy in there (haven&#39;t got time to strip it and clean it until tomorrow tho&#33;)

:o
urs is hotter than mine.
i get 50-55.

The mobo is about 10*c hotter than it should be too.

Woohooo&#33; Stripped everything down and cleaned it out, moved a few things round to get a better airflow and... Mobo 27°C, CPU 52°C - I still think that is too warm compared to some of your temps but it&#39;s a start :D

ya its probably a heatsync problem. could have bad contact...i think you should try the arctic silver 5 and heatsync idea to see what ur temps do...

Your mobo is looking better :D Well done, I think it&#39;s about time I cleaned my case out.

Okay guys one last question (sorry to the original poster - didn&#39;t mean to hijack your thread :( ) - is it better to have the cpu fan blowing onto the heatsink or to have it drawing heat off the heatsink? TIA :)

Most heatsinks are designed...and operate more efficiently...when the fan is blowing into them.
It wouldn&#39;t kill you to try it the other way, but chances are you&#39;ll just switch back.

wow - possibly the biggest topic i created :)

anyway, I took the advice from here and cleaned out my pc - wow, scary how much crap there was. this gave me marginally better results, so then i went full hog and bought myself 2 cheap 80mm fans...ive got one exhaust at the back and one at the front as an intake.

the one at the front wants to be in right cos i couldnt get into the crappy panelling on the front to screw it in, so i had to glue it - lol, blue peter engineering for ya.

anyhow, after my first OC, i was running @:
30°C MB
40°C CPU idle
50°C CPU load (prime 95 torture)

all at 110fsb, 20x mult, 1.5 vcore. = 2200MHz (oced from 2000)

then i added the 2 fans and Im now running @ 2200 @:
25°C MB
40°C CPU idle
42°C CPU load.

I&#39;m pretty happy with these numbers, so after some more stability testing, I&#39;m increasing the clock again. :D


oh, and ive seen an amazing 120mm fan, which would go nicely at the side - just need to borrow my mates dremel...
