Could someone explain to me on why my temps are so darn high Ultra 120 - extreme

[Wizzard005]

Aloha all,

I am not new to PC Cooling, i dont know what the deal is here.


Test setup

C2D e6420 OC 3.4Ghz 1.41Vcore

Cooler Thermalright Ultra 120 - Extreme

Problem 2 x Prime 95 Temps are 70+

idle temps 39c - 41c

Ambent temp: 80 - 85

I read all of the reviews, this is the best air cooler blah blah blah....

I installed it with the LGA775 mount and used Arctic silver 5

I used a small amount, like the size of a piece of rice and spread it all out.

load temps are very high 70c with fan on low and 62 - 66 with fan on high

Low fan setting is 1200rpm high is 3800 rpm

When i put my hand on the heatsink it was luke-warm if that. Why would the temps be so high when the darn thing is barly hot?

You cant screw up the mount as its very strait forward


The only after market cooler i have ever found good with the thermaltake heat towner all copper , forgot the modle number but that thing rocked, when it got hot you knew it was working....

-I am so confused...

Concave base ? I have seen a few TR 120's with crappy curved bases.The TR 120 (e) mounting for socket T isnt exactly brilliant.

if you ever read a certain thread... The TT base is made deliberatly because the intel cpus are made crappy and are concave.

Concave + concave = good.

If you were to lap the TT, it'd be flat + concave = bad.

HOWEVER, if you lapped both the cpu and TT it'd be REAL nice. drop like 6-8 degrees.

Your ambient temps are too high, drop your room temps to 77F and lower and youll see an improvement. As well as, you might have very poor case ventilation.

Yep there is no way it is doing 70c load if you have it seated correctly.

Run a program called Throttlewatch and see if your CPU is throttling because anything higher than 61c makes the CPU automatically throttle. If it is not throttling, then your load is not 70c.

Also use a little human touch. Put your finger on the top of the heatpipe. At 70c it should feel Pretty darn hot. If you can feel SOME heat but not much, it is more likely ~50c.

I have this setup in a Silverstone TJ09, its the only case I really like. I have my water cooling setup in the same case and the temps are high when running 2 x prime95's.

Ifs its because of the amb temp i guess i am out of luck I am like 5 mins away of ordering swifttech's tec cooling for the LGA775

I would order that, but i am afraid of how much heat it may make, meaning, ya i got myt CPU cold, but adding 20+F to my office lol......

Oh i cant wait to move back to the mainland hehe

My roommate is having the same problem, same case as mine, but he has the Extreme P4D 3.2Ghz, it runs at 70 - 90c when OC, we put a freezone on it and it burnt it up! (the freezone)

Your ambient temp also considered high imo.

Go to a Walmart, or what ever you have there, and for $100 get a window AC unit.

 

[ps2cho]

I have ambient temperatures that high when its hot here in southern cali and my processor still stays under 55c. No reason why yours should hit 70c at all for any reason other than not seated correctly, too much TIM, no airflow, or hot air is being pushed into the area around the CPU.

LOL, i have a 10,000BTU already, but during the day its set to 79F I also belive that the Temp programs lie, I can open

TAT, Core Temp, Speed Fan, they all ready something different, so that makes me wonder that one is telling the truth>>>???

Speedfan says core temps at the time of test are 57c

Makes me want to go to the store and make my own thermometer and mount it to the bottom of the cpu... or between the cpu / heatsink..

 

[UglyChild]

TAT and Coretemp read the temps from the Core of the CPU, while others read the temps with in the cpu socket.

If your proc isn't throttling and there's no stability problems, it might just be a goofy sensor or something. Hell my Opteron was reading core temps from its own sensors of 70+ and running stable at a 950 MHz bump for 2 day dual prime tests. Everyone else was like "omg the temps r 2 high!" because theirs under no circumstances reached such temps, but I think its just a quirk of its sensors.

Either way those have gone down since de-lidding it and lapping the xp120, but to be honest that actually killed my overclock by 50 mhz
