New Compoer Fan - CPU Still Hot

post #1 of 7
Thread Starter 
Hi all,
I'm new to the forum and oc'ing in general, so excuse any newbness that I may exude
To get straight to the point, my computer runs hot according to BIOS readings and MBM5.
Within BIOS my cpu reaches 55C, while in Windows it reaches 50C.
My ambient temperature would generally be between 20C and 25C (if not cooler at night time).
Under load, it reaches between 60C and 65C. I'm not oc'ing my computer yet, so the temperatures are taken under 'natural' operating conditions.
I recently installed a new fan and heatsink in place of the stock heatsink, and yet the temperatures read exactly the same! how can this be? I understand Arctic Silver 5 is the best thermal compound, yet this wasn't available at my local store so I used a compound called Unick. (I will purchase and trial some AS5 shortly).

I have good airflow through the case; 2 frontal and 1 top intake fans, 2 rear exhaust fans including the PSU exhaust, 1 Compoer (copper) CPU fan, and 1 currently non-functioning Abit Northbridge fan - soon to be replaced.

On the rare occasion I have experienced random gaming errors, which I believe may be related to my overheating problems.

Oh, I have a Northwood CPU.
Any ideas as to what I could do? Best options?
I have done some research on this forum, but would appreciate any useful advice you could give me.

As long as it stays under 70 you'll be fine... Intel says those chips can handle up to 75 before it starts to lower it's life span.

I tried to find that HSF and nothing came up -- you might want to look into getting a Hyper48 or a Big Typhoon. I'm running at 48-50 full load with this 2.8 overclocks to 3.34. So you should be at at least that if you had a similar HSF.

EDIT:
Did you properly apply AS5 or whatever thermal paste you have when you replaced the HSF?

I followed the directions on the AS5 website, to apply the thermal compound. It's a bit peculiar though - my temperatures were idling at 50C before I touched the stock heatsink, they still idled at 50C after I had cleaned the old compound off and reaplied some fresh compound, and they still idled at 50C after I removed the stock heatsink and installed the new heatsink/fan. No matter what I've tried, it still sits around the same temperature.
As I said above, ventilation through my case is fine, though I think the top fan in my computer is taking air in instead of blowing it out. I tried unplugging it last night (as I can't figure out how to remove the fan and reverse it) but it made little difference to my temperatures.

EDIT: Found SatanSmurf's fantastic guide on airflow within the chassis (http://www.overclock.net/other-cooli...-1-inside.html) which has given me some great ideas. I'm off to buy a GPU cooler for the PCI slot, also I need to investigate reverseing the top intake fan I mentioned.

I've been playing around a littleith my computer, monitoring temperatures etc. Can anyone tell me how hot the cpu heatsink should feel, when the cpu is under load? It feels warm to the touch (when CPU is at 60C).
The northbridge passive heatsink which I just installed gets quite hot when the cpu is under load, and the graphics card heatsinks are simply boiling (still to purchase a pci cooler).
I've tried cleaning up the cables, but I'm really stuck for ideas as to how I can lower my cpu temperatures. I've attached some pictures of my computer, showing the new fan/heatsink I installed, as well as the Zalman passive heatsink for the Northbridge. Also a pic of my graphics card (you can see I moved the modem down a couple pci slots for good measure) and the bundle of cords which I have tried to rearrange.
One of them shows the stock Intel heatsink, along with the sticky adhesive/thermal tab I used to stick on the Zalman passive heatsink to the Northbridge.
Also this link (http://www.upload2.com/?cmd=_viewer&...d1.txt&s=71ae2) is a report from MBM5, showing the rise in temperature from idle to load, when playing Morrowind.

Any ideas what I could change/alter to improve my temps?

AHH, Don't run northys at 60C!! that is way too hot for them, 50C max (for load)!!! anything above that, your doing more harm than good, trust me!

After leaving this for a week or so the temperature has dropped at least four degrees when idle - it now idles at around 46C when in Windows, though it still hits 60C under load. It is quite humid here in Sydney at the moment, but I'm still open to suggestions as to how I could improve my temps (without having to buy and install and airconditioner!).
