Weird temperature drop.

Just some background on my system. My system specs are in my signature (although I'm running 11 x 220 @ 1.7v). I'm using a Evercool WC-202 CPU Block, GPU Block, and the two radiators with a C-Systems 750 Mark II Pump, and a Swiftech Resevoir. My case is a Antec full tower, with a 92mm, 5 80 mm, and a Vantec Card Fan to cool the ramsinks on my 6800. My load temps are around 58-60 degrees, and my idle temps are 51-52 degrees.

Now, today, I decided to pick up a 120mm Vantec Stealth fan to put on a Zalman Bracket FB123 http://www.zalman.co.kr/eng/product/view.asp?idx=15&code=016 in case u need to see it. I mounted the 120mm, and further 7 volt modded it to make it quieter. With that blowing over the Northbridge, the RAM, and the CPU area, I'm currently getting load temps around 47 degrees, and idle temps around 41.

Now.... that's just really weird, because obviously my CPU cooling is the same (Evercool WC-202 waterblock), yet a new 120mm fan on top lowered the temps by 10 degrees.

Anyone want to hazard a guess as to why? Are the temperatures acurrately reflecting the CPU temperature, or is this an anomaly?
 
Well, even the smallest bit of airflow can help a whole great deal...or the probe's busted. Your choice.
 
My theory is the extra airflow is bringing cool air directly to the probe (ie the air is wrapping around, and somehow getting into the Zif socket and cooling the probe more), so I don't think my CPU is that much cooler, just the air between the CPU and the probe underneath it.

Damn why couldn't Asus pull the temperature off the core? I mean obviously they have the hardware for it, they have the C.O.P. (Core Overheat Protection) that shuts it off at 70.

Heh heh, thanks! Yeah, you've got nice temperatures, though for what you've got goin' on! Good stuff.

Yeah.. I was really suprised. To be honest I'm used to my 50 plus degrees. My old T-Bird b and Palimino were all like that, and they were 100% stable and lasted me a while. Never was too concerned. WHen I turned on Asus probed, I thought something was broken.. or someone put ice in my water. :p

Ha ha ha, laughed out loud, literally! Well, you got nice temps. I plan to watercool someday...one of these days. I'll need a lot of [H]elp though...because I don't think I can pull it off myself!

It's not that hard really, just takes some planning, and a bit of research, and some common sense of course. It's a bit more than air cooling, but the returns (lower noise, lower temps) is well worth it.
