As posted on another thread i just got my Papst FM fan.. dissapointed that it wanted to be driven by the PSU directly also that I had to adopt for the louder fan as the other was out of stock I still was keen to finally see what my SLK800 could do with a proper rated higher CFM fan for it...
Being 120mm i had to obviously suspend it away from the heatsink i dunno if this is the culprit for dissapointing results..
Anyways just got it connected.. having a play... I have managed to get 47 degrees idle out of it... my window is open the night is similar temp to last night... I tested my zalman flower coolers original fan on its bracket last night under similar conditions... I am pretty sure that I got a good few degrees lower than this.. I am about to CPU BURN it.. which I know was stable at 51 degrees... I am getting lackluster performance AGAIN out of this papst fan.. its difficult to sit it over the heatsink but its pretty much centred at the moment... I had the fan at an angle just now to have the centre of the fan near as poss to the centre of the heatsink... I have just now brought it back square with it and think that it may have lowered the temp slightly... Anyways I got to thinking.. tho this fan is a very high CFM.. noisy ish.. at 80cfm allegedly... this is obviously spread around the fan... I am wondering if there is a nasty deadspot in the middle of the fan... sitting basically previously over most of the heatsink hence the poor performance...
I just can't believe this... sure i guess its going to make a nice case fan sometime, tho it IS loud.... what am i to do..!? I was expecting at least a 10 degree drop with a quadrupling of CFM...
I think I am going to give up.... I may actually go full circle, back to my Zalman fan.... to be honest I'm tempted to go back to my flower cooler... tho there is a slight improvement in temperature over this model.. In the time it took to type the last paragraph i have been running CPU burn and already it is over the 51 degrees that the zalman 80mm fan had.. gutted
£30 down the pan.. AGAIN!!!!!!
