Temps on Phenom 720 & case temps

According to speedfan/mobo my cpu temp is 41C-ish idle and the core is at 30C

This is on stock clocks. Taking the multiplier up to 16.5 got my cpu temp to 44C and my core to 38.

Stock cooling.

Are these numbers high and if I buy something like a zalman cnps 9900 what temps might i be looking at?

Last: What is the best way to lower the actual sitting temp in my case?

I have 3x80mm fans & 2x120's and I'm wondering if there is anything significant I can do. My frankenstein idea is to get a bucket of ice and sit it in front of the intake fans lol.

Thanks in advance everyone.

Idle doesn't mean anything, at all.

My 720 idles at 40ish, but only loads at 55 because I have a Scythe Mugen 2. Your's will probably full load at 70+ which is dangerous for this chip.

The significant thing you can do is to obviously get off the stock cooling. A 9900 would do, though I encourage you to look around. The only time I would truly recommend a 9900 is if other heatsinks don't fit your motherboard or are too tall for your case. You can get heatsinks that perform better for half the price.

I would love if you could give some actual suggestions.

I'm obviously looking around but since I've never used aftermarket cpu coolers, I'd like some suggestions.

I want the absolute best I can find for am2 sockets. Or near it.

Thanks.

have you ever considered water? Its really easy considering and works like a charm. my 720 in my sig loads at 38core, 43cpu. Works great and is well

I use a Xigmatek HDT-S1283 with a x17 multiplier and cores stays in the mid/high 30s at full load. It is really tall though so if your case isn't very big it may not fit.

I don't have first hand experience with the stock cooler that came with the 720. It was cheap and not meant for over clocking. With that sad, it does make for a good paper weight (btw, the old phenom coolers were much better). :) 

Using a S-1283s 120mm rifle cooler + Artic Silver 5. Yes, it's big. Here is my last setting from the top of my head and my current configuration.

720 @ 3 cores @ 3.6ghz 1.45v
Core: 23c
CPU: 33c
Stress test load (Prime 95, OCCT): 44c
Ambient: ?

720 @ 4 cores @ 3.4ghz 1.40v
Core: --- (enabling 4th core disables core temperature reading)
CPU: 33c
Stress test load: 52c
Ambient: Currently 78c.

Just remember that ambient temperature will affect your readings. It was warm last night and my 720x4 CPU temperature was idling at 37c.
