Unusually high temps for me...still decent tho

so about 2 months ago i bought a bigger, 90 mm fan for my cpu instead of my loud-as-hell 80mm tornado (after having used it for like 6-8 months). im using an slk800u, so the 90mm fans dont exactly fit, tho i read in a few places, and eventually tried this out... u can rotate the fan 45 deg so the corners stick out, but it stays on, so i was happy.

problem was, taht my temps went up much more than u'd think switching from a 84.1 cfm fan to a 64.15 cfm fan would do (plus having done that rotated fan thing, its not touching as much as the heatsink directly as th tornado did). i went to about 34 load to 49 idle. so i put my tornado back on, and it wasnt much better, like 44 idle. so i figured i moved the heatsink a little or something and reseated it (cuz this fixed my probs when i had similar issues like this a few months before). taht didnt do anything....

i kept crashing and stuff, which was weird, cuz even at 49 degrees + a few for load, u woukldnt expect it to crash..and i mean completely frozen. a few weeks later, when i moved my rig to our basement cuz its colder down there (summer is coming soon too), i found out th hard way that the electrical socket down there was bad..and that the monster APC surge protector im using did jack..

so i sent my mobo back in cuz it was fried, and my psu to be safe. i got em back and im back and running upstairs where the pc was orig. located. i have everything back to the way it was originally, and im still at 43-45 idle with the tornado.

my pc doesnt crash anymore, tho ihavent played any games since i got it up, so it might still (ill folow up tomorrow w/ info on taht). the only logical thing i can think of, tho far fetched, is that its due to late spring/summer coming...but 15 degrees!?? i tried to route my cables better today, and its pretty tidy in there like i had it orignially. one interesting thing is that my case temp is 32 degrees, and it was 29 and NEVER moved before when it was working the way i had it orig.

when i rebuilt my pc the other day w/ my new mobo & psu, i noticed that my heatsink looked the way copper does when it gets water on it (turns a little green). i only noticed it cuz my friend had his sp94 that he was puttin in and it was DAMN shiny. i'd LOVE to deem this defective and RMA it knowuing that they wont ahve any stock for slk800u's and then use that $$ to get an sp97 :) but i'd feel bad...sorta... ;p. btw, th system is the one in my sig

so i guess my question is, WHAT THE HELL!?!?

after a day or two burn in its 41 idle.

you think 32 (average) to 41 is feasable in terms of the heat summer's brought? 9 degrees, despite the air conditioner.

and ive resseated the heatsink before w/ success, i dunno whatd change that now, or the last two times...

so you think the heatsink could be defective?!?!? :)

Well, it sounds like you borked something up. Temps are going to go up 8-10C just by breaking cured AS or something like that.

Assuming nothing has changed but your HSF mounting, here is what I would check:
? Are case temps the same?
.... - If not, maybe you unplugged a case fan?
.... - If so, then:
........ ? Chipped Die
........ ? Bad HS mounting
........ ? You upped your Core Voltage
........ ? Your fan on your heatsink is running slower (rheostat?)

Other than this, I'm not sure what else to suggest other than something else has changed too (anything from ribbon cables blocking airflow to PSU going kookoo).

-case temps are 1-2 degrees hotter
-case fan setup is the same
-vcore is the same, not overclocked
-rheostat i used was always on lowest for the tornado (or else, bye bye ears)

and i think the airflow is actually BETTER than before. im using rounded cables like i did before and theyre more outta the way than before. actually 1/2 the time before i used ribbon cables and they still treated it alright.


im 99% sure the die is intact and like it should be

so that leaves the heatsink mounting? i did notice that the white foam pads are one time use only (the ones that come with the heatsink from thermalright) but i stole some from my friend's foam square and cut out some new ones to the same size as the orig (u'll know what i mean if u got a thermalright heatsink)

could it be the corroding copper looking stuff i mentioned before?

I don't see where you mentioned this before. Can you post pics (or email them to me and I'll host them for you)? If your heatsink has corrosion on it, secondly, yes it could be that, firstly, what the hell did you get on it?!

yea i dont ahve a digital camera. the thing is perfect on the bottom. i really dont know how that happened..its just not as shing as it used to be near the top part near the fans, but only on the sides. again, its fine where it meets the die tho.

and ive NEVER spilled anything into the pc or anything like that, so all i can think of is the moisture in the air?!?? tho its pretty damn dry where i have it. i really have no idea what thats about. thanks for ur help thus far

Copper naturally oxidizes over time with air contact. It is not corrosion. It shouldn't have much of an effect on the heatsink's heat dissipation.

From what Jorwex is saying, this is what I was thinking too...

I really don't have any other ideas of what could be different.

I seriously don't think the heatsink is your problem (it MIGHT account for 1C is my guess as an engineer). But honestly, I don't know what is.
