Core i7, is it too hot?

[Rifter]

my specs are in sig. with 22-23c ambients i will idle at 40c, and hit 80-85c under load(linx) and about 80c under prime95.

I have had my CPU hit 90c load temps with 30c+ ambients and it still did not fail. If you do not do DC and your temps stay under 80c while gaming or normal use for you then i would say you are 100% ok.

Edited to add, gaming i will only hit 70-75c and then only in very demanding games(GTA 4, Crysis) less demanding games will stay at 60-65c.

How are the CoolIT systems, are there any worth getting?

i've herd they are the same or very close to the same as the corsair H50, so would probably make little differnce. If i was you and you wanted to get lower temps i would step up to the H70 or go with one of the top air coolers, Noctura NH-D14, Silver arrow, Megahalems. Or of course go all out with a real custom water setup.

Not to thread jack here, but I thought my i7 920 running at 75°C with Folding@Home SMP + GPU3 (on my GTX 480) running simultaneously was way too hot. Are the i7 CPUs able to run long term above 70°C? Perhaps upwards of 80°C even?


On a side note, due to the heat from my i7 and GTX 480 running 100% simultaneously, my PSU was upwards of 61°C. For system health I'm going to wait until winter before I run everything full bore again.

Guess you don't have any urgent computing tasks before winter

I would post in cases and cooling, but I think that H50 can't deal with the I7, not enough capacity. I would use the megahalem, or better.

But I feel like the difference between a Megahalem and H50 are negligible. Well, no. I'm sure you can clock higher and get 5 deg improvements on the Mega, but 5 deg improvement when you're at 95 is still too little.

I would keep Linpack tests under 90.. preferably around 85 or so. That's what I setup my rig to be. Under gaming conditions, I've never gone past 75 I think. Probably low 70s. I need to look at my graphs again.

coolit eco alc is just slightly better than the h50

some graphs for you http://www.hardware.no/artikler/corsair_h70/78230/5

Some say the CoolIT quality is subpar and it's easy to break off the hoses, for example.

I have to say the H50 is pretty strong. It has survived two five foot drops to an aluminum deck - in a system without damage.

I guess Intel thought it was ok to take a step backwards in thermal efficiency for the sake of performance, lets pray this doesn't inspire AMD to do the same.

200 F while gaming and you guys are saying that's ok, this is laughable.

I've looked thru this thread, and have been unable to confirm your statement.

Well he has a really good overclock on a chip that's already clocked high, and you're complaining about some heat? lmao

 

[Haserath]

If you can get your hands on some IC Diamond thermal compound I have seen it lower temps quite a bit.
Just look through this thread to see the results for the guys at tom's: http://www.tomshardware.com/forum/280452-28-diamond-carat-thermal-compound-giveaway
4-5C for thermal compound is pretty good.

There is more than one person in this thread saying a temp equal to or close to 80c is acceptable, look harder.

The oc is great, and yes, if my computer couples as a space heater I'm not a happy camper.

We are not saying its ok Intel is, Intel specs the chips to run at up to 100c so 80c is fine.

Especially since they will hit 80c at stock speeds with the stock cooler.

AMD also specs their CPU's to hit 75-81c depending on model, so AMD can hit 80c too.

So its not like with a huge overclock on a phenom II you arnt going to hit close to 80c. My 940BE running at 3.6GHz would hit 65-70c under load gaming and 75c stress testing, thats only a few degrees cooler than my 4.2Ghz i7.

And as far as efficiancy my i7 is faster than my old setup, both in benchmarking and real world performace, sometimes by a large margin, that would put intel ahead in thermal efficiancy.

I will address the space heater comment, CPU temps have absoutly nothing to do with heat output, the power used by the CPU will determine the heat output from the CPU. For exapmple a 45W TDP CPU under load at 80c will output half the heat of a 90w CPU that only gets to 60c under load, the 90W CPU is drawing twice the power thus outputting twice the heat, even though it doesnt get as hot under load.

So you should be looking at power consumtion if you want to figure out how much heat a system will output. And as far as AMD vs Intel for power consumtion intel is ahead when you take into account overclocking, the Phenom II's are just power pigs when you overclock, take a look at this review, a Phenom II overclocked to only 3.6Ghz pulls more power than a i7 at 3.8Ghz under load. Again proving that intel is ahread as far as thermal efficiancy is concered, at least when overclocking is taken into account.

http://www.tomshardware.com/reviews/overclock-phenom-ii,2119-9.html

For stock speeds the 1366 i7s are 130w TDP, the 1156 are 95w TDP. Putting them about equal to AMD's Phenom II's which are either 95w or 125w TDP chips. They will output very close to the same amount of heat.
