crazy temps after case mods

alright so i punched a hole in my case ot add an 80 mm exhaust fan

I put it in the very top cause my case was getting around 40 at idle and 45 under load with ambient temps around 70f

I have a 478 prescott 3.0

you knew that was coming

anyway before the mods the cpu would idle around 45

now after the case mods im idling a 53 but the case is now down to abotu 35

so wtf

did i bump somethign when i was cutting?

its the stock heatsink and i didnt use any thermal paste
but ive never had a problem till now

when im under load i am hitting 70c which i have set to shut off at
 
damn man, thts high. It is possible that you knocked the heatcink, if one of the clips on the scoket retention module came out then it wont be on tight and wont be cooling much, so do check that the heatsink is all ok. Also check your 3 pin cable going from the fan to the mobo. Just unplug it andf plug back in again. reset the BIOS incase thats screwing with the temop reporting for some reason, check all cables for restricted air flow, and check that nothing is topping the CPU fan from spinning.
 
i havent reset the bios yet cause i dont wanan piss with the settigns again

but its still happening

I have 6 intake fans and 2 exhaust fans plus 1 in the power supply

i unplugged 4 of the intake fans cause they arent really effecttive anyway
the case temps are idling right now at 33c and the cpu is at 49 c

i just have IE open

i took the heatsink out and then put it back on

is it possible the vigbration from the drill f d something up?

can anyone recommend a good heatsink for a p4 478 prescott
 
yea
in high and sight that was dumb

but it was a part of the case that nothing else was near and i set up cardboard behind it to catch debris

the case was on its side and i drilled in the top of it

argg that was dumb
 
after idling for about 15 min im at 47 core 33 case

i can hear something inside that sdounds like its accelerating then bogging down and then accellerating and bogging down

maybe the heat sink fan is burning out?
 
there isnt much of a problem there ;) if you dont hit anything with the drill, youll be fine. anyway,.. make shure the fans arnt placed complete at random.. make them blow a stream of cold air blow through he case.
 
98vert6spd,

I hear that if you take the heatsink off, and then put it on again, the thermal paste can get air in it, and not conduct properly... or did you say you were not using paste?

Eitehr way, try applying something like Arctic Silver 5 thermal paste (you'll need to wipe the old paste off if there is any).

Read carefully the application instructions if you're going to do this, and also ask a few others in here if they thinks its worth doing. Its only about £7, and worth it if it brings those temps down by increasing conductivity from the CPU core to the heatsink.

:)
 
Yea i never used the paste
im going to order some paste and a better heatsink today to see what i can come up with on that
 
Oh, and it's not "high and sight" it's "hindsight" :) I would say that airflow might be a problem. Make sure that you have a nice flow of air flowing from one side of the case, over the CPU and GPU to another side of the case.
 
Lol

Sort out the HSF paste first. Then let us know what your fan orientation is (i.e. how many in-take/out-take fans you have and so on).

JAN :D
 
HIND SIGHT GOT IT

LOL


anyway
there are 2 intake fans on the bottom of the side access panel

there are 4 fans in the front of the case all intake

and there is 1 fan in the top of the case aroudn the middle that is an exhaust
also 1 in the rear about midway that is exhaust

there is also the power supply in the upper rear with 1 exhaust on the exterior and a fan on the inside that pulls air through the psu to exhaust out the back of it

i unplugged the 4 case fans in the front of the case cause they are just adding noise i think

the case temp stayed the same without them

theses are all 80mm fans

can anyone recommend an 80 mm fan that is very quiet?
these are deffinately gettign the air moved but my computer is noisy

also i think im goign to get a new heatsink and fan whatcan you recommend for a 478 prescott 3.0
 
LOL
I BUILT 2 PCS WITH NO THERMAL PASTE AND BOTHE WERE FINE


hell this one has been fine for 6 months

and the other is still runnign from 2 yrs ago

both with no thermal paste

the other is a 2.6 northwood

and it runs plenty cool and silent with no paste
 
Yeah don't worry (form a 'have a I commited a cardinal sin?' point of view), as lots of people dont use paste, but even so, i would recommend it for you!. There are a few different types out there, but i hear GOOD things about 'Arctic Silver 5', and if you buy the SMALLER tube (which of course is cheaper), you STILL have enough in there for say 5 - 6 applications. You only need i tiny bit, as the layer needed is so thin. BEFORE applying it, there is a 'Application Guide' on the arctic silver website, which is a must read if you've not applied this paste before.

I bet those temps come dont a bit after that mate.
 
You have an imbalance in air flow, intake/exhaust. You should have 1 intake and 1 exhaust ratio. Take the side panel off use a fan to blow air into the side and check temps. If the temp goes down, you have an airflow problem, If temps stay the same, you have a hsf or thermal compound problem. I think the reason you have hotter temps after the mod is that you are pulling more hot air up and onto the cpu.
 
yep i used the paste that was included and the core is now at the same temp the case is

i actually got it to idle at 34 and 34
cpu case


i could probably get it lower but i think im barred by the airflow of the case now

but 34 is plenty low for me

i have been used to mid 40s
