which heatsink for my C2D?

I am using a Thermalright XP90c/Arctic Silver 5/Panaflo HO 92mm fan on my e6600 C2D and i get the following temps:

Ambient temp 68F

Idle Temp: 17c

Load temp: 28c

1dle 17c = 62.6 F inside case
load 28c = 82.4F inside case

ambient 68F = 20c -- outside case

Unless you are water cooling its not possible for you to have a lower temperature inside your case than what your ambient temps outside your case are. Not by 6 degrees f....

No matter what thermal paste you are using. Or whatever techniques you are using to cool your case.

Just not possible. If you are using some sort of program to check your temps out what you are using is most likely wrong.
Mobo temperature indicators are notorious for giving misleading temps.

Yeah I tend to believe the thermisters on the mobo are off so what i did was attach a thermal probe to the HSF very close to the place where the IHS and HSF plate meet. I did this about 10 mins ago......

Ambient temp was 67F

Idle temp 19c

Load temp 29c


I do not know how to get more accurate temps than that.

Well, I'm going to remount my CNPS9500 and just tighten the screws until it's snug (not trying to crank it down like before) and see if maybe I was decreasing the contact area by cranking it down. I'll leave it alone after that and wait for my Ultra-120 and panaflow L1A to come.

Thanks for the suggestions and if anyone has more info to share with us about their HSF experiences please do.

My TT BT started to come loose at one point, i was wondering what the hell had gone wrong for ages untill i tightened the screws and the temperature fell by around 25*C :Q

Yes i did feel stupid.

 

[cmdrdredd]

Ok I cleaned my CNPS9500 with 91% Isopropyl and also the C2D IHS. Let them fully dry then installed them again. I made sure just to snug up the screws so they were tight and didn't move, but not crank them down at all. I lost 5c on the temps. That's good. I also dropped the AS5 on the IHS and pressed the HSF down to "spread" it. I only used a small amount. I'm happy so far. I would like to say that the C2D really heats up with increased voltage (to keep stable overclock). This is 100% Normal.

My specs are as follows.
Antec P180 (rear exhaust on high, intake on high, top exhaust on low)
Asus P5B Deluxe/Wifi
C2D e6400
2GB Corsair XMS2 6400 (rated 5-5-5-12)
Zalman CNPS9500 LED (on high)
Seasonic S12 600w PSU

At stock my system runs 42c after heating up to normal idle temps and loads around 50-55 (varies depending on task)
At my current overclock which is 400Mhz FSB(auto voltage), 8x CPU multi giving 3.2Ghz(at 1.34v according to Asus probe CPU-Z reports 1.334v), DDR2-800 Speeds at 5-5-5-12(2.1v)

This makes my idle temps on core temp to 50c at idle and about 60c at load(asus probe reports 49c). My MB temp reads as 34c at idle and when stressing the memory and such it goes to near 40c. My room temp os 80F atm. These are down from my original temps of 55c at idle and 70c at load.

Now I'm not sure whether it was cleaning the IHS and HSF and letting it dry, or the reseating did the trick. I'm happy with the results so far and as the AS5 Cures some I'm sure it may drop slightly even more.

I still believe that the P5B Deluxe is reporting temps on average 10c higher than the actual. I believe this because an identical system using a Gigabyte DS3 is getting about 10c lower temps at load. It could just be something that the BIOS updates can fix.

Just thought I'd let everyone know my findings. I'm gonna put the Thermalright Ultra-120 on hold for the time being. I'll see how this performs as time goes on.

Your temps sound about right to me as reported in your last post Cmdrdredd. I have a C2D 6700 & P5B DH Deluxe Mb, I get about 38c idle & anywhere from 47-50c under load. Ambient is around 75F. This is with No OC & using a Zalman 9500 at the moment.

the thermalright should help keep the board components a lil cooler. i'm not sure about peocessor temps.

I don't believe so because it's a tower type cooler that blows the air (through use of a fan) parallel to the CPU and Motherboard and not down on top of it.

Glad to hear that you are giving the Zalman another chance.
I just installed a 9500 last week and was floored by the temp. reductions over the stock Intel hs. My idle temp with a room temp averaging 74F was 52C and load temps went up to the high 60's. I did check the ihs for flatness- week 24 E6400- and re-mounted the Intel hs a few times with fresh apps of AS5 to no avail.
Immediately after installing the 9500 my idle temp dropped to 34C and hit the high 40's now under load, very rarely breaking 50.
There are several great coolers out there but I am very pleased with the 9500.
I also installed a Thermalright HR-05 nb cooler at the same time which has dropped my mobo temps about 8 degrees as well

I will say that since I have a P5B Deluxe it's impossible for me to get an accurate temperature reading. So I just ran Orthos for 24hours and called it good regardless of what temps I got.

the scythe infinity will beat all. it has 10 heatpipes it logical. it beats the ultra 120

[markymoo]

for good thermal transfer, the pressure between heatsink and heat source must be high!

And then after a year your motherboard breaks because the Infinity is 3 pounds.

Seriously. And to make matters worse, it uses retail C2D HSF mounting system. For a light HSF like the retail HSF, sure. But for a 3lb HSF, you think they would put some effort into making a custom mounting system. I'll stick to my Thermalright Ultra-120 thank you very much.

I still fail to see why it has to be 3lbs when other HSFs work similarly and I've seen many reports of the Infinity just working extremely poorly and not fitting on many systems.

 

[markymoo]

yes well at end of day theres only few degrees between them all lol

if you want that extreme overclock then watercooling is the way...

Wrong. If you want extreme OC 24/7, you get phase. Or LN2 if you want extreme OC record breaking.

And to rephrase what you said, at the end of the day, other heatsinks can do it better than the infinity w/ less.

 

[Atty]

Anyone used stock? If so how were temps (with no OC's)?

 

[markymoo]

im not wrong my friend gets 21c on water thats enough to reach 4 gig. which is considered extreme. as few can reach it.

trouble with hsf is they ok on idle but once you push the voltage they shoot up temp a big margin. you dont get that big leap on water. its proportional rise. abit more cooling is needed to get where most want and water is enough.

fact: theres like 3-4C difference between the top hsfs.

you get around 45 with stock

 

[shiatan]

So what is your thoughts on sound cards. Does using the onboard affect gamplay??

You cannot approach heatsinks from a what if stand point....and its really hard to debate or even converse with people who have no actual hands on experience with the very products that they slam and post things that just are not so!! Common sense in dealing with heatsinks is needed. You of course would not possibly attempt to move your PC say cross country with the heatsink be it the Ninja or the 9500 attached....common sense must prevail. yet just becuase the heatsink has been on your mobo for a year or so does NOT mean the mobo will all of a sudden break apart due to the weight...thats rediculous to assume.
After market heatsink manufacturers take into account all the possibilities that could occur...
case in point...
Scythe as a company had made a copper version of there Ninja...yet due to weight constraints even though it totally blew away the temps the regular Ninja was getting....the copper version never made it to market.....why? One word--weight!!
So don`t think the manufacturers aren`t worried about screwing up there reputation by putting to market an obviously over weight heatsink!!

Again from computer to computer there is NO best heatsink...for some the Ninja works very well for others its not so good....same goes for almost every heatsink.....for some one will work better than the other etc etc...don`t ask me why...thats just the way it sems to work...
