Duron 1200 idles at 55 C

[Weeboll]

Advice please!!

My new duron 1200 with coolermaster DP5-6I11A rated to 1.733ghz fan is idling at 55 deg C !!
The case is a short tower with the mother board behind the power supply - a 300w suntek with variable speed fan and the case had a fan at the bottom blowing in. Everything inside is reasonably tidy and the temps used to be fine with my k6-2 at 600.

My main worry is that this temp is way too high - especially for idle! and what I can do to lower it.

what sort of temps should i be experiancing and will i be damaging the chip at this sort of temp

It's okay that you posted this thread in this forum but I think you will get better answers in the Cases, Cooling and Overclocking Forum.

I hope you don't mind that I move it there!

Couple of questions first -

Is your power supply sucking air into the case, or blowing the hot air out?
Is there any exhaust fans in the rear of your case other than the PS?
Did you use thermal grease or a thermal pad?
What is your overall system temps?

The Duron 1200 is a little harder to cool than the K6/2@600!


Currently, the last Duron 1200 I installed idles at about 32C with a copper Vantec cooler. You should be able to get close to that. I think you probably have an airflow problem since your motherboard sits behind the power supply. Make sure the PS fan is exhausting air. If it isn't, reverse the fan. Also, if you do not have any case fans (rear exhaust) removing hot air from the top half of the case, you will need to add something.

Something like this:

And for the rear PCI slot area:



Hope this helps a little..........

Hmmm,
with a CoolerMaster (the heatsink you have) 55 degrees C is about right, and at a guess says you don't have sufficient airflow going into the case. I also had a CoolerMaster on my Duron 1Ghz (albiet a slightly less capable spec than yours, rated to 1.5Ghz), and it performed under full load at around 50 degrees C if I had no case fans attached. If I put a case fan on, it suddenly dropped to 44 degrees C.

AMDNut has posted a good list of case exhaust devices. I'd also check you are using thermal paste, and not the supplied thermal pad (which is highly innefficient).

Check your vcore.... If your not overclocking it,crank the volts down to lowest setting and try it out. Should knock 8-10c off the temps.

I had a number of cooling issues with my 1200 Duron, but not realy relating to bad over heating.
I installed it in my old case ( no case fans ), Coolermaster HCC-001 HSF, Enermax PSU ( it's got 2 fans ).
Idle was about 46-74C, full load 50-55C.
As summer was around the corner, I thought I would install some case fans ( intake + exhaust ),this lowerd my temps by about 1C across the board.
But because my old case was a thin tinny box I decided to get a better case ( ChiefTec Scorpio ) and installed my rig in to that - the temps did not change that much, but the noise of the case fans was driving me nuts - so I removed the front fan, now it temps have gone down another 1-2C ( without the intake fan !! ).

After all this, I dont realy seem to hae made that much of a difference.

The psu fan is exhausting but only just - i think it is designed to speed up with temps but my case temps are relativily low - high 20's to low 30's so its not getting rid of the air..

I am going to put two 40mm holes in the back of the case and use chipset cooler fans to exhaust the air - can't use a case fan as there ain't enough room!

At the mo i'm using the icky thermal pad that comes with the cooler master, I have thermal paste but its the old skool variety - thick white stuff rather than the silver stuff used these days. Is is worth using or wait till I can aquire some artic silver or the coolermaster equivalent ??

[Weeboll]

another point - the height of the fan means that there's only about 1" to the back of the psu, can any one reccomend the low profile copper coolermaster fan as I think this might help with circulation but don't know how good it is

The "old skewl" white thermal grease is fine, that is what I still use, even on my XP1700+! It will work good for your needs.

As for the copper heatsink, Vantec makes a low profile model #CCK-6027D that [H]ard OCP rated pretty good:



Not sure if you can get it in the UK though.

Hope this helps......

I put two 35mm holes at the back at the same height at the cpu and the temps have already dropped 5 degrees, i'll put a pair of gpu fans over them + use thermal grease on the heatsink and hopefully get the desired effect!

Thanks for the suggestions

You think yours is high. i have a duron 1.2ghz overclocked at 1.3ghz. i am using the heatsink i got with it and an extra 80mm heat fan. And mine runs at 60c. but mine seems to work fine, i hope......
