High temps with the H70


jay05

Recommended Posts

I recently purchased the H70 and getting relatively high temps.

 

The stock heatsink gave me a minimum temperatures of 40/35/38/35 degrees

With the H70 as an intake I am getting minimum temperatures of 36/29/34/30 degrees.

As an outtake, I'm getting minimum temperatures of 36/31/35/32.

This is at stock settings with my i7-950 at 3.06 ghz.

My room temperature is 20C/68F.

 

Is it really worth $110 to lower the temps by 4 degrees?

 

I have tried to reseat the H70 pump with AS5 and still getting similar results. I applied by applying the thermal compound vertically on the cpu and spread an even amount with a credit card.

 

I overclocked to 3.8ghz with the following settings.

I'm trying to get it to 4 ghz but the temps are too high. I will need at least 1.3X volts and 191 BCLK which will generate more heat. Am I doing something wrong here to have such high temps?

you don't need to list your OC details here, this forum is only for cooling.

 

At a max of 61c you have a winner! remember a cpu can run up to 100+c but will be very stable and desired temp are at under 85c.

 

Nobody gives brownie points for "mine is cooler than yours" because there are just too many variables to consider, ambient temp, humidity, case airflow etc.

 

So be happy with your OC, your not in any danger from the CPU and go and do something productive with your computer like calculating the next convergence of the big bang :-)

From your pics you are running at 2GHz? with a Multiplier of 12x? You may want to recheck that Overclock because according to the specs of you OC you have stepping disabled so it shouldn't downclock at all. From the pics you are not running at 4GHz.

 

Anyways I too have been having issues with my OC, I used to have an old I7 920 with a Corsair H50, used it for about a year then upgraded to Asus Rampage III Extreme, Patriot Viper 2 Sector 7 8,8,8,24,2T, Core i7 950 and the Corsair H70. Before I was running at 201x21 at 1.4V at a load of 70c, 71c, 60c, 70c. Now though I am running at 23x 174 at 1.35v but my temps are low to mid 80's on load. I've tried to reseat but I've had no luch lower temps. Pump is working fine and it seems to be seated fine but I was hoping for a lower temp using lower voltage. Kinda has me a bit worried. Going to be taking the system apart tonight and start from scratch again.

are you using the adhesive pads on the backplate, I noticed when I had them on it really hampers the mounting force because it just makes the corners flex on the plate, I could pull on the waterblock and see the backplate flex so I removed the pads and remounted and it seems like there is alot more mounting pressure. if the pads were half as thick they would still hold the plate to the mobo but wouldn't cause the backplate to flex as bad as they do now.

Yeah the pads are on.

 

This weekend I pulled the entire system apart, cleaned the rad aswell as all the fans. Used Arctic Clean to clean the CPU and the H70. Spread out a nice even layer of AS5 over the CPU and another thin layer over the H70 waterblock. Reseated ( no lie the H50/H70 is one of the worst cooler to mount due to the poor design of the screw mounts because the bolt where the screw threads into always comes out of the groove in the back plate and just spins. Hopefuly the H90 ;) will fix this poor design flaw ) the cooler. Idle temps are 40c, 39c, 38c, 39c which is about 10c hotter the I7 920 I recently had with the H50. Load temps after about 30 minutes of World Of Warcraft are 54c, 53c, 54c, 51c. thats what I've been able to test this morning due to the fact I've been fixing PC's all weekend long.... I have not had a chance to run linx or Prime95 yet but judging from what I saw this morning there is no difference.

 

I am however using an Asus Rampage III Extreme and there is an issue with this board and the temperature read out due to Asus poor design of the bios and its a well known issue. I dunno, the H70 really seems like a step down compared to the H50 I was using, louder, cools worse. I dunno maybe its something I am doing but I doubt it. After numerous reseats, etc etc the performance of the cool just seems subpar.

Hi guys.. I can relate to this thread.

 

I just finished installing my new rig - RIIIE, i7 950, H70 ...

 

Tried installing with the stock thermal paste - temps were 45-50 idle - I mean intel stock cooler has the 950 running at the same temps or lower!! On load @ prime95 I got 80c+ in 10 seconds! In Stock?!?

 

Then went on to Arctic Silver 5, remounted the pump unit, tried different positions for the radiator (same slot but tried tubes below and tubes above) - whatever I do though the idle stock temps will not go below 40.. I let the pc prime all night and now it doesn't get above 75c anymore.. what deoes that mean? Thermal paste issue? Pump issue?

 

I'm using a Chieftec Aegis miditower case, and the H70 is installed to the system fan position as intake push/pull, with the above mounted PSU's 14cm fan and the secondary 12cm opt.fan on top doing exhaust.

 

One more thing that's odd - The radiator fans' duty cycle does not affect the cpu temps any whatsoever at all - I even switched them off and looked at idle temps for 10 minutes.. at best the temp rose 1c..

 

My rooms ambient temp might be around 23-25c, since the H70 is doing intake - that should be good right? Is there any chance my H70 is flawed?

never spread the compound on an i7/5/3 read the proper instructions linked above and allow 200 hours before expecting AS5 to do its proper job.

 

there are 168 hours in a week so report back in 10 days when the AS5 has been applied properly and allowed to cure.
