CPU hot even with water cooling

Ever since I bought the X2 4200+ with Asus A8N32-SLI mobo the CPU has always been running hot compared to what other people posted. Today I have installed watercooling and my temps still seem to be very high. On idle at 2.5GHz it's 36C (core temp) and on load it goes up to 47C (core temp). I've seen quite a lot of people posting their temps in mid 20s for the same CPU.
When I was running my sytem on air using Cool & Quiet at 1.1GHz idle the temp was 36C and 51 on load (2.4GHz).
What might be the reason for these temps? Is my room hotter than everyone elses? Temps do drop a few degrees when I open the window but I don't think they will drop below 30C.
 
whats your ambient temperature? neither air nor water can cool below ambient, so if you have a hot room then you will innevitably have a hot cpu
id say the majority of people look at how closely their coolers keep the CPU to ambient temps, if you read online reviews, they will also often quote the difference between the temp of the cpu to the ambient temp, anyway im rambling off the point
 
sounds like bad IHS contact with the cpu core.

does the temp shoot up really fast when you put load on?

with watercooling it tends to shoot up a lot slower than air. its more gradual.

if its going up fast its a sure fire bad contact

I haven't got away of measuring my ambient temperature

A fridge thermometer will do the job, £1 from pound shop. Does seem hot though, is case cooling sufficient? My 4400+ X2 @ 2.2ghz idles at 25-30 degrees with CNQ disabled. Ninja cooler.

I just checked it now and the temp went up from 36 to 43 in around 20 seconds and then stayed at 43.


One other thing that i've noticed between air and water cooling temps is that core temp and CPU temp were the same on air but on water cooling the core temp is around 3-4C lower than CPU temp (that's on idle) and then at load the core temp is usually a few degrees higher than CPU :confused:

Even if I take the side panel off and put a few strong fans on the temperature does not change very much.

Need to get some of these fridge thermometers.
 
I have the latest BIOS, all 3 previous BIOSs reported these high temps.

I've googled this and it seems that the temps seem to vary a lot for this processor. Some people have reported idle temps of 29 on stock HSF and some even up to 60C. The temps seem to be very inconsistent. Maybe it depends on the mobo as well.
 
If you've reseated loads of times and there's no difference then my money is on the temp sensor.

Leave your pc off for awhile, power on and go straight to the bios. If the temps go straight to 36 then you know there's something up with the probe. There should be some kind of warm up time if its working correctly.
 
43c isnt that bad. Its in the safe zone to me :) Still perhaps a littler high. Have you seated it correctly? If you have probly IHS contact :( if it continues perhaps try and RMA? or just get a decent cooler on it.
 
Anything could cause that, bad mounting, bad core --> IHS contact, high ambient temps, mobo temps read incorretly, core temp not calibrated correctly... etc etc etc.
 
I got myself a thermometer today and the temperature in the room with a small window open is 28-29C. I think this explains why the CPU temps are this high.
 
ambiant +6-7 for idle is good.
maybe think about having a exterior mounted rad (I piped the water out of my office to an external rad mounted in the shade but in the wind.
