Been lurking on this forum for a while, its very good...unfortunatly im posting for help rather than to add to the buckets of knowledge on here :-s
I have the Temjin TJ06 case, running with stock fans, a gigabyte LGA775 motherboard with a Pentium 2.8 installed in it.
When i first put the system together, I couldnt install the windtunnel due to how i had to route the 4pin ATX power lead, and i stuck with the stock Intel cooler until there were more 3rd party ones on the market and i could make a more measured decision on noise/heat levels. im returning to playing with PCs after a break of a few years and wanted to get used to the 'base' setup before i started playing with making the system silent and so on.
Recently i thought i would start moving towards cooling the system more efficiently and quietly and after much toil and consulting this thread in particular and various reviews, i figured that as the silverstone heatsink seems to have been designed to be used with this case, i would plump for that. I had to source a NT01 v2 which would fit my LGA775 socket and so im not sure wether the figures quoted on here are so relevant as they were taken with a 478 socket, but anyway, im sure what im getting isnt right. I ordered an extension cable for the atx 4pin at the same time so today ive gone from no tunnel and the stock intel cooler, to the tunnel plus the NT01v2. Unfortunatly due to the placement of a few chips and things on the motherboard blocking the base of the heatsink, ive had to orientate it so it goes 'along' rather than 'across' the tunnel as this is the only way i can fit it. other than that, the system is pretty much as i intended when i ordered the heatsink.
As a referece my system used to idle at about 35-38 deg and peak at almost 50 when burning CDs in the background of browsing several webpages and running a spychecker at the same time. I also use the system to play games which i presume also drives the heat up further but ive neglected to measure the chip temp when im flying round corners on Colin McRae Rally!
I installed the new kit today, and now find that the temps gone through the roof. On first boot-up with the new kit, it idled at around 45 and when i started burning a CD it shot up to the sixtys, peaking at 71 deg! Obviously not the result i wanted!
Ive been using the monitoring software that came with my m/b and wondered wether there was something amiss with how that was measuring things so just to be sure, i also went into the BIOS to check there, and that reported an idle temp of 61 deg...
So where have i gone wrong? does the orientation of the heatsink (90 deg from the ideal setup) really have such a negative impact on its performance? and would getting some fans to mount on the heatsink possibly counteract that if so?
